ASDM 6.4 for ASA 5505

[sunbeltadmin]

Created a STATIC NAT and Filter rule for a remote connection to our new phone system but can't seem to get it to work. any suggestions.

[Rahul Govindan]

Seems to be failing NAT. Can you paste what you have added as config?

I masked the outside interface IP

[Rahul Govindan · Accepted solution]

The only static rule that I see is this:

static (inside,outside) tcp interface 35400 10.1.2.150 35400 netmask 255.255.255.255 

You also have the ACL allowing traffic to the server from the outside:

access-list outside_access_in extended permit tcp any host 10.1.2.150 eq 35400 log disable 

You have a pre-8.3 configuration. That means, you have to have the translated ip address on your ACL. Reference this guide:

http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/113024-asa-82-port-forward-00.html#allowuntrusted

Your ACL should look like:

access-list outside_access_in extended permit tcp any host <outside-interface-ip> eq 35400 log disable 

After making this change, run the packet-tracer from the CLI using the following command:

packet-tracer input outside tcp 1.1.1.1 12345 <outside-ip address> 35400 detail

[sunbeltadmin]

i'm going to assume this worked...

If we use a Cable Modem for our internet do i need to port forward on the modem to point to my outside interface?
