Re: ASA 5505 SSL Vpn Issue

bgibson.PT · ‎10-13-2010

Here is the problem I have. I can connect to the ssl vpn with Any Connect just fine. Split tunnel also seems to be working. I can ping the inside interface of the ASA unit. I however can not ping or access any other way hosts on the inside network only the asa's inside interface. I included a copy of my config. If someone could help me figure out what i'm missing it would be greatly appreciated.

Sure, your NAT exemption access-list is incorrect.

Instead of:

access-list inside_nat0_outbound extended permit ip 10.99.99.0 255.255.255.0 any

It should be:

access-list inside_nat0_outbound extended permit ip 10.10.80.0 255.255.255.0 10.99.99.0 255.255.255.0

Then pls remember to "clear xlate" after the above changes.

Hope that resolves the issue.

Mad the changes put i still can only ping the inside interface

of the ASA. Any other ideas?

What are you trying to ping? Pls make sure that the host doesn't have any windows personal firewall enabled as that normally blocks incoming connection from a different subnet.
