Hello all, I'm in the process of setting up a client server network using Windows SBS 2003 including ISA. I have three client computers that need to connect to the server via Windows VPN. I have managed to successfully connect each of the client computers to the server individually, however when I try to connect more than one client computer the second computer returns an error 721 the local computer did not respond. If I disconnect the first computer wait for about ten minutes then try to connect the second computer it will be successful. Can anyone suggest a possible reason for this problem, the server has 5 CAL's four of which are free.

It could be a number of problems.

Check in RRA that there are sufficiant ports available.

I have also in the past had problems with some routers only being able to pass through one VPN connection at a time.

What router (S) are you using?

Are you using ISA as your firewall connection to the outside or are you using something else for your firewall?  If something else, what are you using?

Ref: NeilParbrook.
In regards to the RRA can you shed some light on what this is. Thanks
The router used at the remote site is a Netgear DG834G with V1.05 firmware. It does appear that this could be the problem, I have seen a number of forums on the topic

Yes I am using ISA as the firewall connection to the outside

RRA is Routing and Remote Access.  If this was set up from the wizards it should be OK.

Have a look at this post...

It looks as if this guy is having the same problem as you.  I don't know weather you could go down the firmware upgrade and use the router for VPN.  If I were you and this is the problem then I would buy a new router for your remote office. Something like a 3com office connect which I assure you won't have this problem and are cheapish.

Hope that helps

Neil

Hello, this problem has now been resolved. It transpired that there is a limitation within the Netgear router that will only allow one outbound VPN pass through. This was resolved by swapping the Netgear modem/router over for a Zyxel 660HW-T1 modem/router this is capable of such feature. Thanks for you assist anyway
