MSExch 2000 through firewall

I have the following problem DC with Win 2000 Server and MSExch2000 on it. It works just fine till the moment i turn on my firewall. Than it refusees to accept mail, it sends just fine but it refuses to accept. I read in Microsoft Knowledge Base Article - 148732 about it, but it concerns only MSExch Server 4.0 5.0 5.5, the things are slightly different in MS Exch2000.
What I want to know is where exactly in the registry I have to make changes to assign statically ports through which i will recieve mail. Please, help me!

Someone replied to this post in another group - please don't multipost.
However, the gist of it is, it's not likely to be a problem with your
server, it's more likely a problem with your firewall rules. Check to ensure
that traffic on port 25 inbound is forwarded to the internal IP of the
Exchange server.
