I would need someone to test something for me.
I have been working with Micorsoft support ( for hours) on an vpn port issue and we are at odds.
our server was running PPTP vpn connections with no problems but I have to change to L2TP
for various reasons.
On my server I can telnet (telnet localhost 1723) and I don't get the port not open error ,so it is working.
I go through the procedure to setup L2TP with a pre-shared key I also get the MS tech to look at the settings, so everything looks right.
But from the server I cannot telnet localhost on port 500 or 1701.
could someone who is running l2tp try to telnet to 500 1701 from their server and see if they get an answer???
The MS tech just turned around and blamed my router or the xp client or SP2
any help would be appreciated.
