Solved: ASA 5505 VPN is not responding.

sivapkd100 · ‎06-05-2010

Here is the asa 5505 Configuration. VPN is not responding. When I check my IP address in the website "whatismyip.com" it is showing A.B.C.X. I believe it shoud be A.B.C.A. Also I am not able to access (https://A.B.C.A) firewall from public untrusted network. Please help .

Thanks,

siva

Sivakumar,

Could it be that your ISP is doing some sort of proxy or NAT for some connections - like http you mentioned?

A simple packet capture on ASA will show you if the ASA is receiveing those packets.

(You can apply same logic for to the box and through the box traffic capture, except you don't need to capture on two interfaces)

The problem has been figured out. Firewall configuration is correct. But there was a small coniguration missing in netopia router, i.e, I had to turn off NAT functionality. Now all right.

Thanbks for responding to my thread.
