SBS 2003 failed VPN Setup\Connection

[TimKidney]

Hi all

Hope you can help me out...

Have set up a VPN connection on a SBS 2003 using the Configure Remote Access wizard, accepting all defaults and naming VPN connection vpn.<company website excluding www> (details of server name\domain etc to follow)

Have also used the Configure Firewall wizard to open relevant ports on my D-Link DSL-2740B and even logged into config page to check the VPN PassThru box and Port Forward the following ports to the Servers IP address:
External Port Internal Port Type
47 47 TCP
50 50 TCP
500 500 TCP
1723 1723 TCP
1701 1701 UDP

Server is a SBS 2003 single server (DHCP, AD etc) single static NIC.

Ive manually setup the connection on Vista and Windows 7 as well as run the .exe SBS creates for you but fails on Error 800 failed to connect which seems to be a generic message which could mean a lot of things?

Really stuck now as have tried many things.

m not 100% sure the ISP IP address is a static one, could that be an issue?

How can i tell if the client connection is even reaching my router?

Ive run a tracert from the Client and it stops somewhere out in the web?

Ive also spoken to 1 and 1 who host side\email etc and they say we need to upgrade to a dedicated server package to allow VPN connections which im sure is not right?

Internet is with BT Business

Any help\guidance id be very grateful.

Cheers, Tim

See if you can telnet to the box on port 1723.

Normally GRE and 1723 is all you need if you'll settle for simple PPTP.

Also, the router from the client location also needs to be enabling GRE too, not just on the server end.

Does anything else work on the server, like OWA? If so, then you know you have the right IP address.

Also, you may have named it vpn.company.com, but is that what you're typing into the external client? Have you created an external DNS A-record that maps the hostname "vpn" to the public IP address of your server? If you haven't, your external clients won't be able to find your server.

Hi Tim
Just a thought, cos I had the same problem when I first started with 2k3 SBS.
I installed Server 2003 and then installed all the updates.
Apparantly if you do this VPN will fail every time.
You MUST configure your VPN before you install any updates.
I had to wipe my system and start again.
Best of luck
Phil


I'm studying hard every day, so why is the learning curve appear to be heading downwards?
