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

Hi Bro
Can you add these commands and this should work.

!!!!!!!!!!!!!!!!!!!! This is not important to remove but just do it for now. Later you could add them back. !!!!!!!!!!!!!!!!!!!!!!

Basically, when Inside wants to communicate with Highline or vice-versa, you’ll need to enable “NAT Exemption” i.e. nat (nameif) 0

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

08-21-2012 03:37 PM
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.
Regards,
08-21-2012 04:53 PM
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.

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
08-21-2012 05:28 PM
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
08-21-2012 05:37 PM
Here's the Highline version as requested. Not sure I understand the "next step would be the captures". I hope you'll be able to give some guidance on that... Thanks again for the help.

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)

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.

Hello Geoffrey,
capture capin interface inside match Tcp host 192.168.100.2 host 192.168.1.254 eq 3389
capture capout interface Highline match tcp host 192.168.100.2 host 192.168.1.254 eq 3389
cap asp type asp-drop all circular-buffer
Then try to go from 192.168.100.2 to 192.168.1.254 RDP
Afterwards post the output of the following:
sh cap capin
sh cap capout
sh cap asp | include 192.168.1.254
