When i port forward 53 TCP and UDP on my Router to my DNS server i lose all internet anyone know whats causing this? been using this configuration for ages My internet loss is complete with a random ping return every 1in50 using my dns servers and public ones

My situation is BT Buisness Hub 3 Router on 192.168.0.3 a Win 2k8 server on 192.168.0.1 and a sendmail linux box on 192.168.0.2 i have the 1 static ip configuration and port forward smtp to the mail server and DNS 53 to the windows server that runs DNS

Really scratching my head on this one can anyone offer an idea at a solution or advice on an alternative configuration

Cheers Jon

Can you use your default configuration or that is already your default configuration? If that's the case, it is possible that your router is already malfunctioning which needs to be fixed or replaced.
