NAT Port forwarding problems!
I'm using Qwest DSL with a Cisco 678 DSL router. I'm on PPP with a dynamic IP. My IP doesn't change, I always get the same IP. I'm using NAT on the Cisco as I only have the one IP address. Port 53 UDP and TCP is forwarded to my Redhat box running Bind. Internally my RH box takes all DNS requests without a problem resolving everything as expected. yahoo.com, google.com all resolve without issue. You can ping my domain and my alias's I have defined for it and the DNS server returns the correct IP. When you try and use my DNS server as your primary DNS server external to my network it returns the IP of the DSL router for every request. If you ping yahoo.com it will return the IP of the DSL router as the IP of yahoo.com. I know there is communication back to the DNS server because it will resolve my aliases for my domain. Here's the odd part. Even with an internal IP scheme setup in the DNS server it still returns the DSL routers IP for those aliases. Currently I have it set up to return the DSL routers IP. As you can see my setup seems to have some issues. The problem is with NAT and port forwarding and PPP. Somewhere in that mix lies the issue. Any help would be appreciated. My IP is: 184.108.40.206. My domain is spokanerc.net. One of my aliases is: ns1.spokanerc.net. Any help is appreciated!
