Okay, here is the situation. I have a Cisco router running NAT. I've got a Name Server setup (and running great)on the inside of the NAT. The problem, as you've probably already figured, is that the outside can't find my name server. I've tried an "ip nat outside static" mapping of ports tcp 53 & 42, and udp 53. This doesn't seem to work! I was just wondering if anybody knew how to accomplish this. Thanks in advance, BrEeZe

Port 53 is all you really need. The command on the router should look somehting like this... ip nat inside source static tcp (local address) 53 (internet address) 53 extendable ip nat inside source static udp (local address) 53 (internet address) 53 extendable Of course eacj of these commands would be on line. Also is your name server setup for your external addresses? What os does the DNS server run on? Hope this helps, let me know if you have more questions. You can email or come back here, if want help faster email me.
