My LAN has 2 different subnets 10.1.1.0 and 172.16.10.0 which is my DMZ. When I place the SME Mail server in the DMZ I have verified that the Mail server is able to reach outside as well as can send and receive mail. I cannot use outlook however as I get 550 error relaying denied. I have gone into the network and manually added: 172.16.10.0 with the gateway having to be 10.1.1.1 which makes sense as the instruction say "Router" should be the IP address of the router on your local network via which the additional network is reached." I cannot add 172.16.10.1. I can ping it from the mail server it is open. Not sure if that is my issue or not.

If I try to add 172.16.10.1 I get the error message "router address is not accessible from local network."

DNZ is resolved locally, the router I use Juniper SSG allows me to add my policies so that I may have access between the segments just fine. Any help would be great.

I guess I problem is unique? No one seems to want to reply.... :-x
