Setup using two NICs in SBS 2003 R2 with a TZ170

I have setup Windows Small Business Server 2003 R2 using two NICs.  One NIC is connected to a SonicWall TZ170 and the other NIC is connected to the LAN.  Everything is configured properly to allow the users access to the LAN and the Internet.  The issue is that I am having a difficult time getting the TZ170 configured properly to allow e-mail traffic to and from the Exchange server.  I used the Wizard on the TZ170 to setup access for port 25 to go to the internal LAN address of the SBS.

Any ideas as to where I am going wrong or has someone else setup SBS 2003 using two NICs behind a SonicWall TZ170?

If you have an external firewall, you can turn off the windows firewall, and see if that fixes your issues.


I hope this helps !

I went through the SBS Wizard to Configure e-mail again and selected to not turn on the Firewall.  I still am unable to send e-mail out.

At this point I am going to have to switch back to a single NIC solution.  It just seems to me that there should not be this big of an issue setting SBS with two NICs behind a hardware firewall.

You should be configuring the SonicWall to forward port 25 to the IP address of SBS's external NIC. The SonicWall can't see the internal NIC, and therefore can't forward anything to it.

I had port 25 forwarded to the external NIC but got nowhere.  What I think I really need to do first is remove the SonicWall altogether and try with just the two NICs.  At least I will know if I have Exchange working properly.
