Re: Vpn Setup Problems

I'm afraid you're going to have to give some more information for us to help you.

What sort of VPN are you using? (IPSec?)
What is the device at the other end of the VPN connection?

When you try to start a connection what do the VPN endpoints say in their log files? (The _other_ end from the one starting the connection is the place to start looking, did it receive anything at all?)

Sorry I can't help straight away but I'm sure with more info we can get you going...

Ok iam new at this vpn thing sorry

I'm not familure with the differences of IPSec and PPTP. What i would like though is that i can access my network at work from home.

The 3com Router is suppose to be the Vpn Server i suppose.

I was using the windows xp vpn connection to try to connect to the VPN Server (3com Router)

Ah, right, now I get you.

On the 3Com router under VPN you should enable the L2TP/IPSec server. When you select the L2TP server it will I think show another box in which you need to enter a "machine password"... or some name like that.

In windows it's a bit more tricky to find this setting - set up a VPN connection, then under the properties for the connection you have to click the 'security' tab then there is a button marked "IPSec Settings..." which you then click "use pre-shared key for authentication" and enter that machine password in the box. Now OK all the boxes, put your username/password in the connect dialog and hit 'connect' and hopefully it will go. If not, post the 3Com unit's log files (feel free to obscure any IP addresses/passwords shown in the files)

Note that you should have UDP ports 500 and 4500 allowed outbound at your work or the 3Com unit won't receive the data.

Good luck,
Bob
