VPN to Microsoft IAS Server via Netscreen 25.

[bladesman]

Hi All

I am trying to connect to a MS IAS server from my network, my PC sits behind a Netscreen25.
I'm using the standard MS VPN connection on my PC to do this, but it keeps comming up with an error 721.

I know the connection works as i have another ADSL connection, seperate to my office network and the VPN works fine if i use this to connect through.

All ports are open to go out, but only specifics one comming in.
I think the problem is that i don't have a particular port open.
Any idea's as to which port this is.

Cheers

Hi,

Do you have access to the Command Line? The reason I ask is because it's a good idea to debug the traffic to see what is going on. If I was to guess, it's probably using IP Proto - 50. Let me know.

Rgds,
