Hi I have a VPN connection to a clients network that I maintain.  The server is behind a BT Router which is configured to forward VPN traffic to the server.  Up until now the connection has been working fine.  How ever I went to connect today and the connection just times out on verifiying username and password.  This has happened before after a power cut at the server end but when I got my client to restart the server I could connect again.  This is not the case this time!  Last week I configured my clients home laptop to connect to the network and that is all working fine.  Im stumped!  Please could you help!

I believe it is 721.  However I have got my client to turn off the router and turn it on again and I can now connect.  It is looking like the router will only accept one VPN at a time how can I sort this out?

I'm not familiar with that router, but a quick search shows that there are problems with VPN if you don't have the latest firmware, which is always a good idea to check anyhow:  http://btbusiness.custhelp.com/cgi-bin/btbusiness.cfg/php/enduser/cci/bt_adp.php?&cat_lvl1=426&cat_lvl2=427&cat_lvl3=440&p_cv=3.440&p_cats=426,427,440&p_faqid=7280

Thanks for the advice Jeff.  I think my client wants to go ahead with the change to the cisco router anyway.  Is it possible that this router can only take one VPN at a time as this is the standard one that BT send out with their Business broadband package.

As I said, I'm not really familiar with that router... it is very conceivable though that a router would limit the number of PPTP connections.  The Cisco 857, for instance, has a limit of 10 users.

I was wondering if port forwarding was the problem.  You see I have set up the current router to forward all incoming VPNs (port 1723) to my VPN server is ther any way that I have not configured this properly and it is preventing two VPNs from being forwarded. Do I need to forward any more ports?

What do you mean your "VPN Server"?  Do you mean your SBS?

sorry yes I mean My SBS server.  Also I just got a cisco 857 integrated services router.  Followed the instructions to to configure it so I could use it instead of the BT one.  But after I have made all the changes and clicked finish it just freezes and does absolutely nothing.  I left it for 20mins Nothing!  So I went into task manager to close the windows and reconnected to it through the browser and guess what no changes had been made I had to put in the factory password to get and try again and it did exactly the same. Any suggesstions?

If you're asking about how to configure this router overall... beyond the scope of getting your VPN to work, then you really need to post a separate question.

I have asked a seperate question for the router configuration.  Just need to know if I need to forward any more ports to allow more than one vpn? Or if my current config Port forwarding incoming 1723 to my SBS server is enough.

All you need is 1723 AND GRE Protocol 47 (which is not port 47).  GRE is sometimes called "VPN Passthrough".
