My server isn't allowing port 25 among other port traffic to get to it. I DON'T have a firewall installed on it or between it since it is a test server and even when I connect the nic directly to a hub with another PC on the same network and subnet mask, I can't ping it or telnet to port 25. I can ping from the server to the workstation though. Any places I should check? I have eliminated my ISP from the mix when I connected the NIC directly to a hub and had a PC that it could ping.
I could connect to the server via messenger and I could browse the web from that server.
