I have a new ASA 5520 installed, with much thanks to this group, and its working perfectly.
I did notice one caveat that isnt quite right, and cant figure out however.
When we had a linksys as the firewall, it did NAT and DHCP for the clients and in that DHCP pool we had DNS servers specified. Same is true with the ASA, however with the ASA, clients from within the LAN can not resolve our own domain. We can get to every other domain in the world except our own! We need to refer to our servers as 10.0.0.x/xxx instead of domain.com etc.
Any suggestions? We do not host our own DNS, our ISP does this for us, however we could. When we did we had other problems with PAT.
Thanks in advance.
