I am currently running a 2003 Exchange Standard server. Router IP is 188.8.131.52 incoming smtp is 184.108.40.206. Reverse DNS is setup correctly to 220.127.116.11 yet when the server makes an outgoing connection it is coming from 18.104.22.168 and being denied for rDNS due to the incorrect IP. How do I make Exchange use the correct outgoing IP for this to work correctly? Or do I have to change my NAT to move the Exchange server to the Routers IP?
