ASA 5505 - ALL Outside Traffic In

jdlampard — Mon, 11 Mar 2019 19:35:33 GMT

At a branch MPLS site I have an ASA 5505 (Security Plus license and provides DHCP) with about a dozen devices behind it (PCs, phones, and a network printer). The MPLS is the only connection outside of the office until it is replaced with a dedicated Internet and site-to-site VPN connection in a couple months.

I need all traffic from the main office to flow through the ASA (without statics) to the branch systems and I don't want outbound traffic translated.

I removed the NAT and global and thought/hoped simply changing vlan2 (outside) security-level to 100 would complete the objectives. No luck. I added same-security-traffic permit inter-interface - again, no luck.

Is there a way to achieve the goal other than using firewall transparent (it's remote and from what I understand once changed I'll lose access to it and it would have to be changed back when MPLS is replaced with Internet).

The only option I see is to set up site-to-site VPN across MPLS. Hopefully I'm missing something and there's a better/easy way.

Thanks for your help.

Regards,

Don't quite understand your topology, can you pls share a topology diagram?

From what i understand, branch office and main office is connected via MPLS, and internet is also via MPLS. You have ASA at the branch office and would like to route traffic from the main office destined to the internet towards the branch office. However, if internet is also via the MPLS, traffic from the main office will never be routed towards the branch office because it will go straight out directly via the MPLS if the internet connection is routed via the MPLS.

Unless if i understand your topology incorrectly, you won't be able to force internet traffic from main office towards branch office if they are all using the same MPLS to route to each other. The only option as you said would be to set up site-to-site vpn.

5505 -- ISP-managed MPLS router -- MPLS cloud -- ISP-managed MPLS router -- HQ Firewall

I simply need any traffic originating in HQ and destined for systems behind the Remote 5505 to pass thorugh the 5505 without any firewalling on the 5505... like it's a switch.

ASA is running Version 8.2(1).

Seems my previous, incomplete, response will not update.

5505 -- ISP-managed MPLS router -- MPLS cloud -- ISP-managed MPLS router -- HQ Firewall

I need traffic originating from HQ and destined for the Branch systems behind the 5505 to pass unfiltered... like the firewall is a simply a switch.

ASA is running 8.2(1).

Thanks for your efforts!

Re: ASA 5505 - All ALL Outside Traffic In

Jennifer Halim — Sat, 15 Jan 2011 05:03:55 GMT

OK, so the internet connection is at HQ, and for your branch office to access the Internet, it will be routed via the MPLS towards the HQ, and out to the Internet via the HQ internet connection?

Your statement: "I need all traffic from the main office to flow through the ASA (without statics) to the branch systems and I don't want outbound traffic translated."

--> do you mean, you would like traffic from branch office to flow through the ASA (without statics) to the main office, since the Internet connection is at the HQ?

If that is correct, assuming that you have inside (security level 100) and outside (security level 0) interface on your ASA at the branch office, then you can configure the following:

access-list nonat permit ip any any

nat (inside) 0 access-list nonat

Then "clear xlate", and traffic should not be translated from branch office towards the main office.

Re: ASA 5505 - ALL Outside Traffic In

Jennifer Halim — Sat, 15 Jan 2011 05:07:42 GMT

Yup, that NAT exemption statement should do:

access-list nonat permit ip any any

nat (inside) 0 access-list nonat

And to initiate traffic from low security level (outside), ie: HQ, towards high security level (inside), branch LAN, you would need to configure ACL to permit the traffic, and apply that on the outside interface.

Re: ASA 5505 - ALL Outside Traffic In

jdlampard — Sat, 15 Jan 2011 05:14:49 GMT

Thanks for the replies.

Forget about the Internet. Simply put. All systems in HQ needing to communicate with Branch systems behind the 5505 should not be filtered by the 5505. As it is right now, I would have to set up statics and an ACL for the outside interface on the 5505 which is no good.

Also, in my original post I indicated having removed the nat and global statements, set security-level on vlan2 (5505's outside) to 100 (same as 5505's vlan1 - insdie), and enabled same-security-traffic permit inter-interface.

Re: ASA 5505 - ALL Outside Traffic In

Jennifer Halim — Sat, 15 Jan 2011 05:18:59 GMT

OK, if you don't want to configure any NAT statement nor ACL, then you would need to configure the following on the ASA:

1) Security level needs to be the same on both vlan 1 and vlan 2.

2) Configure: same-security-traffic permit inter-interface

3) Remove all the NAT and global statement as well as the static statements.

4) Configure: no nat-control

5) Remove access-list applied to any of the interfaces (especially the outside interface).

Traffic will then flow freely in both direction with no translation as well no requirement to configure any access-list.

Re: ASA 5505 - ALL Outside Traffic In

jdlampard — Sat, 15 Jan 2011 05:32:00 GMT

Traffic from Branch to HQ is not the problem - I have NAT under control. How can I "disable" "filtering" of traffic coming from HQ to Branch? It all needs to pass untouched and without having to configure statics and inbound ACL (although I already have one which didn't help).

interface Vlan1

nameif inside

security-level 100

ip address 10.30.20.2 255.255.255.0

interface Vlan2

nameif outside

security-level 100

ip address 10.30.8.2 255.255.255.0

...

same-security-traffic permit inter-interface

...

access-list outin extended permit ip any any

...

access-group outin in interface outside

...

Traffic coming from HQ to Branch is still filtered. Short of setting up a site-to-site VPN or using 'firewall transparent' what can be done to allow HQ-to-Branch traffic to pass the 5505 untouched?

Re: ASA 5505 - ALL Outside Traffic In

Jennifer Halim — Sat, 15 Jan 2011 05:34:10 GMT

Remove "access-group outin in interface outside".

If you have same security level on both inside and outside, you don't need to apply any access-list.

Re: ASA 5505 - ALL Outside Traffic In

jdlampard — Sat, 15 Jan 2011 05:45:41 GMT

I only added the access-group when same-security-traffic permit inter-interface didn't work. At your suggestion though I have

removed the access-group... still no love. Verified security-levels are both 100 and that same-security-traffic is

inter and not intra

*scratching head*

Re: ASA 5505 - ALL Outside Traffic In

Jennifer Halim — Sat, 15 Jan 2011 05:48:14 GMT

Sorry, when you say it didn't work, what do you mean? Where exactly is it failing? If you run packet capture on both outside and inside interface of the ASA, do you actually see the traffic from HQ towards branch?

Re: ASA 5505 - ALL Outside Traffic In

jdlampard — Sat, 15 Jan 2011 05:56:25 GMT

It didn't work = traffic originating from HQ destined to Brach systems (for example, web interface on a printer, RDP to a Windows box, ping to whatever) stops at the 5505.

On the 5505...

packet input outside tcp some_hq_ip some_port some_branch_ip some_other_port detailed

...result is allowed.

Re: ASA 5505 - ALL Outside Traffic In

Jennifer Halim — Sat, 15 Jan 2011 06:03:17 GMT

If packet tracer allows, it doesn't seem to be issue with the ASA configuration.

Can you share some logs that says it stops at the ASA? and also run packet capture on both outside and inside interface of the ASA. Need to confirm where exactly it's failing.

I assume that you are trying to access hosts in 10.30.20.0/24 subnet, and those hosts have default gateway configured to be 10.30.20.2?

Also, if there is any personal firewall, etc on the hosts, please disable it as it normally does not allow inbound connection from different subnets.

Re: ASA 5505 - ALL Outside Traffic In

jdlampard — Sat, 15 Jan 2011 06:22:26 GMT

Yes, trying to communicate with 10.30.20.x hosts and their gateway is 10.30.20.2. I can't easily sniff on either side of the 5505 (remote and no technical people at the site) but I can demonstrate clearly that this is a firewall issue.

Prior to the firewall being put in-line there was an unmanaged switch (failing which is one of two reasons the firewall was put in - the other being MPLS is going to be replaced at the remote site with broadband). With the switch in place I could access anything I wanted from HQ to Remote... access web interface on print server (no personal firewall to interfere), RDP to all Windows machines (yes, firewall is enalbed but RDP and ICMP are allowed), I could ping anything, and 4-digit dialing on phone calls from HQ to Branch... take the failing switch out - put the firewall in - now no connectivity from HQ to Branch. Again, statics and an ACL isn't acceptable.

If I can't get this work then my only options are site-to-site VPN or 'firewall transparent' which I think presents other configuration challenges for me with it being remote.

A quick look in the 5505's log shows...

%ASA-2-106001: Inbound TCP connection denied from 10.99.21.21/10001 to 10.30.20.20/80 flags SYN on interface inside

10.30.20.20 is the print server. I don't know when the log entry appeared relative to the many changes I have made (other than the entry immediately above it shows me chaning outside's security-level to 100.

Re: ASA 5505 - ALL Outside Traffic In

jdlampard — Sat, 15 Jan 2011 06:26:29 GMT

Error Message Decoder (support tool on site) didn't help with 106001 - I understand the problem but don't know how to fix it. The tool suggested nothing needs to be done which is obviously wrong.

Re: ASA 5505 - ALL Outside Traffic In

Jennifer Halim — Sat, 15 Jan 2011 06:39:06 GMT

Depending on when the log error is, it is seeing traffic from the HQ (assuming 10.99.21.21 is your HQ host) towards your print server (10.30.20.20) on the inside interface, which is wrong. If traffic is coming from HQ, it should be seen on the outside interface.

So, yes, definitely a routing issue. How does traffic coming from outside appears on the inside interface? Traffic from the HQ should appear on the outside interface of the ASA, right?

Defintely not configuration issue on the ASA. You would need to check hop by hop and make sure that the ASA has been correctly connected, ie: correct VLAN on the switch, etc.

You can run packet capture on the ASA itself, and that can be performed remotely.

On the ASA, assuming that traffic is coming from 10.99.21.0/24 subnet towards 10.30.20.0/24 subnet:

access-list cap permit ip 10.99.21.0 255.255.255.0 10.30.20.0 255.255.255.0

access-list cap permit ip 10.30.20.0 255.255.255.0 10.99.21.0 255.255.255.0

cap cap-out access-list cap interface outside

cap cap-in access-list cap interface inside

Then send the traffic across, then share the output of the packet capture:

show cap cap-out

show cap cap-in

There is only one physical and logical path in/out of Remote and that is through ethernet0/0 (outside, vlan2). I am obviously SSHed to this interface to manage the device and can ping the firewall from various MPLS sites (10.99.0.0 is HQ - 14.2 is a firewall and 21.11 is a server) which appears in the capture. What doesn't sppear in the capture is that I can't ping anything behind the 5505 at Remote.

The default route on 5505 is 10.30.8.1 - the provider-managed MPLS router.

This isn't a routing issue - I can get to the firewall and *everything* worked with an unmanaged switch before replacing it with the firewall.

Now for some more supporting info, this is from the 5505 to the printer server...

S*   0.0.0.0 0.0.0.0 [1/0] via 10.30.8.1, outside

Definately something with the firewall. Again, if I need to do site-to-site VPN or firewall transparent that so be it, although the VPN seems like a heavy-handed band-aid and firewall transparent will be a huge nuisance. Certainly there is a non-VPN, routed-mode solution.

One last look in the log praying for something of value and the best I could come up with is...

Jan 15 2011 07:42:39: %ASA-6-302016: Teardown UDP connection 2917 for outside:139.78.133.139/123 to identity:10.30.8.2/65535 duration 0:02:01 bytes 48

The firewall has NTP configured sourced from the Internet and it too works (although this is outbound which is not my problem but it highlights that from the firewall across MPLS and then to the Internet from 10.99 HQ site works).

I have my log set as follows...

logging enable
logging timestamp
logging buffered informational

I appreciate you working with me on this!

Jennifer Halim — Sat, 15 Jan 2011 08:16:20 GMT

Your capture result is showing that you are actually pinging the ASA outside interface (10.30.8.2), so that would not help us in identifying the issue.

Pls kindly test the following:

1) Clear the capture - clear cap cap-out && clear cap cap-in

2) Ping from HQ towards hosts in 10.30.20.0/24 network, eg: try to ping the print server and your XP machine

3) Browse to your print server on port 80 as tested earlier.

4) Then grab the output of "show cap cap-out" and "show cap cap-in"

I fail to understand how VPN will change anything base on the description provided so far.

2) Ping print server at Branch (10.30.20.20) from HQ host 10.99.21.11 - times out

3) Traceroute to 5505 (10.30.8.2 - outside interface) from HQ host 10.99.21.11 - completes

4) Traceroute to print server at Branch (10.30.20.20) from HQ host 10.99.21.11 - times out beginning at 5505
