Okay, I'm missing something simple here but have yet to figure it out. 1. I published (2) internal SMTP boxes to outside "live" IP addresses. I can access these internal servers on port 25 just fine on thier 'public' ips. 2. I can telnet to the SMTP port of each other's private IP address. (ie. 172.16.x.x to 172.16.x.x) Problem ====== When I try and telnet from one SMTP server to the published "public" IP of the other SMTP server, the connection is denied. I've created a rule to allow internal network to localhost network for port 25 but it is still failing. Any suggestions on what to look for next? Thanks in advance for your kind suggestions! :) -paul ________________________________ This email is confidential and should only be read by the intended recipient.
