nat problem on sendmail server
I have a dilemma on my hands. I have always run my private servers on a dsl line. I used my own routers and never had an issue with mail. Partly due to the fact that my router translated the NAT IP (192.168.1.x) into a routable IP.
Now, I have had ATT U-verse installed. The router that came with U-verse, a 2-wire all in one type thing (modem,hpna,router,julianne fry maker), has a bridge in it that makes my static IPs local to my NAT IPs. My problem is that my mail server is trying to route my 192.168.1.x client addresses as routable IPs. and of course everyone is denying relay. The router is dummy like so there is very little help there to make the NAT IPs appear as a routable address. I have tried adding a hostname entry (192.168.1.x client.local) on the server and that didn't work. I am just not savy enough to come up with a solution around this.
