ASA 5510

Unanswered Question
Jun 16th, 2010

I am trying to telnet between two locations and  i am unable to inbound telnet to the ASA

router. I can outbound to the other location.

I created access rules in the ACL on the ASA for the source and destination. But I still see the IP being denied in the log.

Is there another place I need to input those IPs to allow access?

Should I clear the ASDM cache?

Thanks for your help,
Jackie

I have this problem too.

Hi,

If you create the appropiate rules to allow telnet traffic through the ASA, it should work.

Make sure that the rule that permits telnet is above any deny rule (blocking telnet), remember the ACLs are read in sequential order.

Please post the output of:

sh run access-group

sh run access-list

What code are you using?

Please include the source and destination for the telnet that is not working.

Please include which translation(nat/static) you are expecting to be used by the traffic, I believe you are saying it is from internet to the inside of firewall right?

Since your access-list has object groups, please include the details of the objects so that we can see if there may be issue there.

Please include any log you get for the source or destination when you try to do the traffic flow that does not work .

Maybe you can also use packet tracer (available on code 7.2 and later) to simulate the traffic, and see where it fails :
