Can't telnet into Exchange Server
Posted on 2004-04-18
Hi recently I setup an SBS 2K3 Server at my office. It all setup mostly well (Except my companyweb website which didn't get installed and that's even with the new CD3 that they sent me but that's another story). Anyhoo we have a registered domain name say www.abc.com and it's setup to redirect any mail to the the domain to a mailbox that the exchange server is currently popping from no problems. Anyhoo I want to change the MX record for my domain to go straight to my exchange server. But before I do that I wanted to make sure that my exchange server was available. So I tested with telnet. When I "telnet www.abc.com 25" the screen pauses for a little bit and then brings me back to a dos prompt. Does this mean my server is not available to the internet (SMTP wise). I can successfully get terminal services, remote desktop, outlook web mail and VPN. Why can't a simple port 25 port forward work?????
The server has two network cards
Internal is : 192.168.1.254 and External is : 192.168.0.3
I have a Netgear DG834 Router that is 192.168.0.1 and I have set port forwarding for all the usual stuff for remote access INCLUDING Port 25 all to 192.168.0.3
The router has the latest firmware installed.
Anyhoo I noticed if I telnetted locally on the server I can "telnet 192.168.1.254 25" and get the blabber at the top. If I "telnet 192.168.0.3 25" the PC pauses for a little bit and then brings me back to a prompt just like when I try from the net??
Somethings' amiss. Do I need to sort of bridge the two adaptors in my server?
