http://forums.fedoraforum.org – I ran into an unusual problem. I had to change all the IP's at work when I installed openvpn-as so that the IP's wouldn't conflict with home users. After the server rebooted, it no longer accepted smtp connections from outside itself. Here's some of the checking I've done: netstat -nl | grep 25 Code: tcp        0      0 0.0.0.0:25                  0.0.0.0:*                  LISTEN iptables -L | grep smtp Code: ACCEPT    tcp  --  anywhere            anywhere            state NEW tcp dpt:smtp The server is on a private IP with the router forwarding all traffic from one of our public IP's to the private IP. I can telnet into port 25 using the public IP from the server, and I get: Code: 220 mydomain.com ESMTP Sendmail 8.14.3/8.13.8; Tue, 26 Jan 2010 16:07:20 -0800 *** Domain name changed to protect the innocent... Yet if I try to do the same from outside, I can't connect. I am still receiving e-mail. But I can't send mail from any computer except the server. I used to be able to send mail from anywhere.
