Subject: ports over VPN
Anyone have a list of the ports used by Outlook to Exchange 5.5 over
vpn?
thanks.
Well it would be within the VPN right. 1723 for IKE and 500? (client
specific I dunno) for the tunnel, then Outlook would run as per normal on a
LAN where it would establish a connection to Exchange server on 135 and then
get a random port above 1024 blah blah... That's my understanding.
At the moment we are... and then figured out Outlook wasn't working.
*sigh*.
Damn virus

What type of VPN are you using, i.e. Microsoft, cisco
routers/pix/concentrators? Are you blocking any ports on the routers

You are kidding, right? A VPN would wrap all traffic through either a
PPTP or L2TP connection. It doesn't use standard ports. PPTP VPN's use
IP Protocol 49 (port 1723). L2TP uses UDP Protocol 17 and ports

Have a look on your machine for a file called services, usually under
c:\winnt\system32\drivers\etc it lists all the most commonly used ports.
