DNS Rewrite

[oneirishpollack]

I understand that DNS rewrite will not work with PAT, but is there some other workaround?

We have a "guest" network on the inside that points to an external DNS server. The DNS reply comes back with the outside address of the server in question. Since PAT is being used for this address and DNS rewrite does not work, what are my options since the ASA will not allow the traffic to travel inside-outside-inside?

Option 1:

change hosts file to point to the internal IP.

Option 2:

If there is a NAT device in front of your "guest network", do a destination NAT.
