Problem between Adtran Netvanta 3305 and Cisco 5510

kbrubaker · ‎08-24-2010

Hello, I have a Cisco 5510 ASA in Routed Single mode using an Adtran Netvanta 3305 MPLS router's external interface as the Outside route (0.0.0.0 0.0.0.0 67.X.X.X 1).

From the Adtran, I can ping all external IPs, but can't ping or access some IPs from the ASA. I can ping and traceroute to the Inside and Outside interfaces on the Adtran. There are about 5 websites I can't ping or traceroute to from the ASA, resulting in users being unable to access those sites.

The problem sounds like the external ip address of your asa , which i think is also used as your PAT / nat overload ip address is being blocked by those sites. best way to check it is , assign a different ip address ( static nat ) and then try to access that web site.

Thanks
