I am implementing a PIX firewall and I am trying to move my DNS servers over to the PIX. When I create the static nat mapping on the PIX and move it over, DNS resolution stops on the server. I can ping IP addresses on the internet and I can ping the IP addresses of Sprint's DNS server, which is my ISP. This DNS server is used for external DNS for some of our customer's websites.
In a nutshell, DNS resolution is not working once I have the server going through the PIX. On other server I can send them through the PIX, but I have to put the internet address of the DNS server on them for them to work, but if I put both DNS servers through the PIX nothing works.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
