I have been searching on the internet for months now to get my server right but I cannot figure out how to do this. This is my scenario:
I have the regular ATT Fast Access Small Business DSL with a Netopia 3347 Modem/Router Combo. Right now I have my Windows 2003 Server with 5 static Private IP Addresses, with IPMaps to my 5 Public IP's. These Ip's are 220.127.116.11/246. Each of these IP's are connected to one of my private IP's. On the Kerio Mail Server I have 5 domains I mail from. Each domain is bound to one of the private IP's. I can access all the the domains except for one now because of DNS issues but that's neither here nor there. My concern is that when my mail server mails back out through SMTP it's only mailing from 18.104.22.168 it's ignoring the rest of the IP's. I can tell you my Netopia 3347 tells me the 22.214.171.124/246 are not part of the network. The reason is the only way ATT could show me how to setup the Static IP's was to map one IP to each port on the back of the Router but this also leaves no wireless devices aloud to be connected and still restricts my being able to run all my domains from my mail server on different IP's.
Now I recently acquired a TZ 190 Sonic Wall, which I'm hoping can solve my problems. Or is can what I want be done from the netopia? Can what I want be done with out adding 5 nic cards to one PC.
