Exchange Test Lab
Posted on 2006-07-12
We have set up an Exchange test lab in one of our offices. Have the server up and running and two clients attached to it in the domain. These are all sitting behind a Linksys router with a 192.168.x.x scheme. The router is then connected to a switch that connects to my LAN and SonicWall firewall with a 10.x.x.x scheme. I have the router set so that the LAN side is the 192.x.x.x and the WAN side is 10.x.x.x so that I can get Internet access. I am able to get out and send e-mail out no problem.
However, when I try to reply from my LAN e-mail back, the e-mail never shows up. I have SMTP being forwarded on the Linksys router to the IP address of the Exchange server. I also have the SonicWall firewall forwarding SMTP to the IP address of the Linksys router. In theory it sounds like it should work, but it's not. Can someone please explain what I'm doing wrong here or what I'm missing. I need to get incoming e-mail to work in order to really test Exchange for our organization.
Any help would be appreciated!
