ASA 5510 config issues
Posted on 2013-11-02
I am in the process of updating my internet and have done the 5 other branches no problem, but I'm stuck on this ASA with what seems to be DNS related issues.
My ISP is using this new 5IP service in which they give me a private IP to place on my ASA and they forward requests from my 5 public addresses to me.
Now I have everything configured and if I statically assign the ISPs DNS on any machine in the network I have internet.. GREAT.. so when I send the ISPs DNS as a forwarder on my DNS server, the IPs wont resolve. Try to Ping google's IP unsuccessful. so it seems that my Primary and Secondary DNS servers cannot reach anything outside.
I logged onto my ASA and try a Ping from the outside interface to google. it works
try a ping from the inside interface to google.com and it fails
try a ping from the inside interface to googles IP and it fails.
so I try the packet tracer from inside interface my DNS server IP to googles IP. Accepted.
