Inter interface communications not working on asa 5510 v 8.2.2

GEOFFREY BARKER — Mon, 11 Mar 2019 23:44:44 GMT

Howdy,

ASA / Cisco Novice here:

I have an ASA 5510 attached to 2 internal networks. Everything is working except communications between the 2 internal interfaces.

I can ping the FW from either interface and I can ping hosts on both networks from the CLI but can't get any traffic to pass.

I'd like to open the connection to all traffic.

A picture being worth a thousand words, below is the physical network and a cleaned config (Note that I have highlighted the commands that I think should make this work).

Can anyone see what I'm missing?

Regards,

Geoffrey

Re: Inter interface communications not working on asa 5510 v 8.2

siddhartham — Tue, 21 Aug 2012 21:22:25 GMT

Can you do a packet trace from 192.168.1.100 to 192.168.100.100 and check on which step the ASA is dropping the packets.

Since you don't have nat control enabled, I don't think you will need the below statemetns

static (Inside,Highline) 192.168.100.0 192.168.100.0 netmask 255.255.255.0

static (Highline,Inside) Highline-inside Highline-inside netmask 255.255.255.0

siddhartham — Tue, 21 Aug 2012 22:37:11 GMT

you did a trace from 192.168.1.X to 192.168.100.X, is that right? according to your config the packet should match the below statement

static (Highline,Inside) Highline-inside Highline-inside netmask 255.255.255.0

not sure why it matches against nat (Inside) 1 0.0.0.0 0.0.0.0

Just to make sure can you try the below command and paste the output

I initally posted a response where I did not get the source and destination right. I deleted that post though. On the other hand, I may have run my trace from the inside interface...

In any case, here's the results of the cut and paste you requested:

Hello Geoffrey,

Access-list denied hmm, have you make any changes to the config since you created this ticket?

If yes, please post it back

The ACL should not be dropping this packets.

GEOFFREY BARKER — Tue, 21 Aug 2012 23:53:34 GMT

Hi,

Strange right?

I just did a careful line by line comparison of the current config and the one I sent. Apart from enabling Telnet on the Highline interface, they are identical. I also just ran another packet trace and got the same results.

Thanks for any thoughts on this weird problem.

Geoffrey

Hello ,

As a test please remove the following command as its not need it

no access-group Highline_access_in in interface Highline

That should not make a difference but I would like to have a clear configuration

Run the following packet-tracer:

packet-tracer input inside tcp 192.168.100.20 1025 192.168.1.20 80

Re: Inter interface communications not working on asa 5510 v 8.2

Interesting... For an unneeded access-group, removing it sure had an affect on Packet Tracer output.

After removing that line - current Packet Tracer Output below. Oddly, though the traffic is no longer blocked, I still can't RDP (for example) through the FW.

Hello Geoff,

I am doing the packet tracer from the inside, the one you did before was this one:

packet-tracer input Highline tcp 192.168.1.100 1025 192.168.100.1 80

Can you do it and if by any chance it says allow our next step would be the captures,

Regards,

Julio

Re: Inter interface communications not working on asa 5510 v 8.2

Julio Carvajal — Wed, 22 Aug 2012 00:41:58 GMT

OH GOD!!!

Well that happens because of not using your own stuff

I was ussing the packet tracer that Sid provide us "packet-tracer input Highline tcp 192.168.1.100 80 192.168.100.1 80 detailed"

This packet tracer is pointing to the Ip address of the inside interface and ofcourse its not going to work!

Traffic to a distant interface is never allowed on the ASA no matter what.

Hmmm well I need to know the ip address of the RDP computers you are using ( both client and server)

Regards,

Julio

Oops. Been there.

I'm trying to (amoung other things) RDP from 192.168.1.254 to 192.168.100.2 and vice versa.

Just in case, it might be worth saying again that I can ping both of these hosts from the CLI on the firewall.

Re: Inter interface communications not working on asa 5510 v 8.2

Julio Carvajal — Wed, 22 Aug 2012 03:15:10 GMT

Hello Geoffrey,

Doest not look like an ASA problem to be honest with you

On both interfaces we can se the same amount of packets...

As you know each tcp session gets established by following a three way handshake. In this session we only see a SYN packet comming from the client to the RDP server that let us know 2 things:

1- The packet is getting lost or dropped on the way from the ASA to the server

2- The server is not allowing that traffic ( Please tell me you have the wonderful Windows Firewall disabled )

If the windows firewall is disabled please go ahead to the server and download and install wireshark this will let us know what is happening and as you know wireshark does not lie so if the packets are reaching the server and he is replying back we will see it.

Re: Inter interface communications not working on asa 5510 v 8.2

GEOFFREY BARKER — Wed, 22 Aug 2012 04:36:41 GMT

Well, the ASA is not off the hook yet (and I so wanted it to be).

Wireshark sees no TPKT traffic when I attempt to RDP from 192.168.100.2 to 192.168.1.254.

It does however see tons of packets when I successfully RDP from 192.168.1.101 to 192.168.1.254

Windows Firewall is indeed disabled.

The only equipment between 192.168.1.254 and the firewall is a managed Netgear switch. I looked at it's configuration and found that it has a single default VLAN that is active on all ports so I assume the packets are not being lost there.

Also will say again that I CAN ping from the CLI on the FW to 192.168.1.254. Weird one isn't it?

Thoughts?

Can you ensure you do the following and let use know what's the outcome

access-list Inside permit ip any any
access-group Inside in interface Inside

no global (Outside) 3 Server2-Outside netmask 255.255.255.255

Note: Those workstations in Inside and Highline can access the Internet, am I right?

Hey Will,

Nice avatar...

I did all of that but no change.

You are correct. Workstations on both subnets can access the internet through this ASA.
