W2K - accepting port forwarding

We had to reset our router today when our ISP went down, and I am having trouble getting the router and W2K to talk to each other again.

Internally, the server is running fine. For example, Exchange 2000 is delivering mail and sending mail. But, when you try to connect via a POP account for our outside users, or OWA, or Terminal Server...no such luck. You get a "Cannot Find Server" message.

All of our records are configured correctly (A, MX, etc) as this was working this morning. I think there's just an item or two I have forgotten to set back up after resetting the router.

Any thoughts?
 
Your router was doing NAT I think (right?)
Check NAT settings. If you have requests from outside to your w2k server ( thatis inside) then your NTA router has to be instructed how to do this (adding things like: requests to this public IP have to be routed to my internal IP address of that server, or x,y,z service to be routed to an internal server). I'm saying in this general case because every router has it's own way to configure this. Gia Betiu

I did a little more research, and here is what is happening:

Everything is pointing at our router:
mail.domain.com resolves the propoer IP address
owa.domain.com resolves the proper IP address
terminal.domain.com resolves the proper IP address

I can also ping the IP address that they point to.

I have the router set to forward traffic for port 80 and 25 to our server. Our server is 192.168.1.3. It would seem to me that traffic is not making it through the router...correct?
 
You need to get it to forward POP3 as well - port 110.
 
I now have the following ports forwarding to my server:
25
80
110

I still can't access owa.domain.com and terminal.domain.com. I get a 404 message in the browser.

mail.domain.com seems to be working, as folks outside our office access our Exchange Server as thru POP3 are getting their mail fine.
 
can u ping your internal servers by IP and/or DNS? (IIS, Exchange)?
 
forgot one important thing. can you ping from outside your router?
 
I can ping the IP internally, but not externally...
