Hi All

I'm a newbie who has been asked to set up a simple PPTP vpn network so that remote clients can access a small busines network.

I have the sbs connected to the adsl router (that has a static IP external address), I have ran through the configuring the isa 2004 firewall as a vpn server contained in the vpn deployment kit, but I am not sure exactly what to do on the clients. I have tried a basic make new network connection (connecting to the external IP static address of the router) but I cannot connect to the network (get an error 678).

Help will be greatly appreciated.

Cheers

OCB

Hi
Did you forward protocol 47 (GRE), and port 1723 ū TCP to the external IP of ISA Server?

Note: in some chipper routers you ad to forward all ports and protocols because you just canĘt forward protocols

Thanks for the reply jdl. I followed the instruction guides in the VPN Deployment kit, there was no mention of protocols and ports being forwarded to the ISA server.

I'm afraid I'm not sure what you are on about.

The router is a 2wire 1800HG, used with the BT Business broadband share service.

Routers usually let you get out but not in unless you make the necessary configurations
Can you access the router configuration????
If you can and just for debug proposes try forward all ports and protocols to the ISA external IP address (donĘt worry ISA is a great firewall) then try to access your net work
Sorry I just cant be more explicit, in Portugal I donĘt have 2wire 1800HG nor BT Business broadband share service.

Then let me know

This should be as simple as running the Connect to the Internet wizard and then adding the users to the VPN group in active directory. If you have done this and it isn't working, then you may have the port issue J describes.
