Sorry to ask but I am in a time crunch and need to get this working today. I am trying to get the Inside interface to talk to the LegacyLAN interface. I could use the help thank you and sorry if this has been asked befor. Thank you for any help.

Re: ASA 5510 communication between 2 same security interfaces.

Marvin Rhoads — Sun, 16 Feb 2014 18:15:05 GMT

Do you have a security plus license activated? That's required on a 5510 to allow traffic through the box to the management interface as you are attempting with your configuration.

(Note that the newer X series do not allow this at all.)

Other than that it appears pretty good (your access-list entries "permit ip any any" make the following ACEs ineffective - I assume you have those in for troubleshooting).

Sorry for the dumb question but how do I check?

I think this is it?

I changed the Intefaces as follows:

interface Ethernet0/3

description LegacyLAN 192.168.119.X/24

nameif LegacyLAN

security-level 100

ip address 192.168.119.1 255.255.255.0

Richard Burts — Sun, 16 Feb 2014 19:48:43 GMT

Yes you are correct that you found a display that verifies that you do have the Security Plus license.

You tell us that you changed it around so that the Legacy LAN is no longer on the Management Interface. But you do not tell us if this change made any difference in the behavior. And I am not sure what the behavior is. Since you are asking I assume that the interfaces are not communicating. But can you give any specifics about what is going on that might help us understand the problem better? I started to ask if you see anything in the logs - but then I looked at your configuration and do not see that logging is enabled. Enabling logging might be helpful in finding the issue.

I will also offer a comment about your access lists, such as this one

access-list Inside_access_in remark Implicit rule: Permit all traffic to less secure networks

access-list Inside_access_in extended permit ip any any

access-list Inside_access_in extended permit ip object-group Tunnel_Networks object-group DM_INLINE_NETWORK_3

access-list Inside_access_in extended permit ip 10.132.3.0 255.255.255.0 192.168.119.0 255.255.255.0

If the access list starts off with a permit ip any any then all other lines are redundant and will have no effect since everything is already permitted.

[edit] I just noticed that Marvin has already commented on the access list permit any any issue. sorry for the duplication.

rickgomez2003 — Sun, 16 Feb 2014 19:56:52 GMT

Yes you are correct the I am unable to get trafic to pass between the 2 interfaces. I will enable loging. Both networks can get to the internet. Could you also give me a acccess list the will permit these network to get to the internet that is alitel more sucure. Thank you all for the continued help.

Richard Burts — Sun, 16 Feb 2014 20:33:45 GMT

It is interesting that both interfaces can get to the Internet but not to each other. When logging is enabled it may give us a better clue about what the problem is.

Part of the config suggests that there is (or will be) VPN configured. I do not see any VPN so far. Can you clarify this?

I suggest that we wait to discuss changes in access lists until we have resolved the problem that is preventing communication between these interfaces.

Marvin Rhoads — Sun, 16 Feb 2014 20:37:34 GMT

Just use the packet tracer wizard from ASDM or the packet-tracer cli utility. It will tell you what would prevent a given flow. Use an address on the respective source and destination networks and something like tcp/80 to test.

rickgomez2003 — Sun, 16 Feb 2014 20:43:37 GMT

You are correct there is a tunnel currently that functions, and we will be implemetnting client VPN also. Thank you for the help. I will post the logs shortly.
