Exchange Behind a Webramp and Wingate Proxy 1

[MarkRobinson]

I've got two devices between Exchange Server and the Internet. Wingate, a Proxy Server, and a Webramp which acts as a firewall and binds modems.
Ive opened ports for POP ans SMTP and Exchange E-Mail works Fine... I can send and recevive e-mail from the company side.
I can't attach to Exchange from the outside.
I've opened TCPIP port 135 (Someone said that was Exchange Control Signals). When I try and attach through the internet I cant CHECK NAME... A network error is preventing...

Anyone know what ports Exchange uses?

Are you trying to create some type of VPN/RAS connection from the outside Outlook/Exchange user to the server? As you might know Outlook communicates with Exchange using RPC, in which case you'll need to enable the appropriate TCP/UDP ports for RPC and maybe NETBIOS.

Do you know whwre I could find out what ports those are?

You might start with the following Microsoft Knowledge Base article:

XGEN: TCP Ports and Microsoft Exchange: In-depth Discussion

#Q176466

Search on the KB within Exchange and NT for tcp ports or udp ports if you want to find more.
