SMTP / Port Forwarding not working
Having an issue with what I thought was your average port forwarding. Just recently upgraded my Netgear WNDR3700 to DD-WRT v24-sp2-std. Everything was going smooth until I decided to open ports to forward to my one server (SBS 2008 Standard). I noticed right off the bat that I was not able to get email via my Exchange 2007 Server via port 25, so I did a reverse DNS lookup on my IP and 3 out of 4 ports were reverse looking up but not SMTP (25).
Has anyone seen this before or am I missing something? I thought I was experienced in this realm but maybe not. I have included a screen shot as an attachment for reference of what exactly I'm talking about.
Thanks in advance for any help and support.
Sincerely,
Mike Johnson
