Does it log anything? I think there is an option for "detailed VPN logs" in the log setup page. If the 3Com unit logs anything about you trying to connect then turn on those details, try once more and then post the resulting logs here and hopefully I can tell you what the problem is.

If it's not logging anything then either the client is not setup correctly or something is in the middle blocking your data.

You haven't told me what that router is, so I can't help tell you how to open them.
If that router (the work one, not the VPN server one) is a 3Com OfficeConnect device then the chances are you'll configure it under the "PC Privileges" section. It would probably be enabled by default but you need to check.
If it's another manufacturer then look in the firewall settings for outbound port settings and make sure UDP 500 and UDP 4500 are allowed.

As for your windows machine's firewall... you might need to open the ports but the firewall should prompt you. If you hit 'connect' and it asks if you want to block or unblock then unblock it!

As for configuring the VPN connection on windows:
windows control panel->network connections
then left-hand-pane click 'create a new connection',
hit 'next',
select 'connect to the network at my workplace,
select 'virtual private network connection',
enter a name for the connection,
select 'do not dial the initial connection',
enter the IP address of the 3Com VPN server unit,
make a choice of yours or anyone's use,
hit finish.
Then go for 'properties',
click security tab,
IPSec settings button,
check 'use pre-shared key for authentication' and type the key...
click ok etc back to the top,
enter username and password and hit connect!

Then if that doesn't work we'll need you to download and post the log files from the VPN server!

And also do i need to open those ports on my windows xp machine?]]> http://www.dslreports.com/forum/remark,18382227 Wed, 23 May 2007 10:15:25 EDT http://www.dslreports.com/forum/remark,18381458 rjs1003 : 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]]> http://www.dslreports.com/forum/remark,18381458 Wed, 23 May 2007 04:34:13 EDT http://www.dslreports.com/forum/remark,18377764 Sigmaiota : 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)]]> http://www.dslreports.com/forum/remark,18377764 Tue, 22 May 2007 15:20:43 EDT http://www.dslreports.com/forum/remark,18376744 rjs1003 : 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...

But the problem is that when i try to set up a Vpn Connection to my other office it is not connecting at all. The user names and passwords are all in the router. It is on a static Ip adress Range. I had to do this because the equipment which it connects to is Static.. Any help will be greatly appreciated.]]> http://www.dslreports.com/forum/remark,18376151 Tue, 22 May 2007 10:41:08 EDT
