When connect to SBS 2003 VPN, lose local internet connectivity.

Hello,  I have recently setup a vpn for one of my clients on SBS 2003.  The vpn connection works fine except for one thing.   Access to all network resources are fine.   When my client connects to the network, they lose internet connectivity.  I know it has something to do with the IP address assigned when connected.  

SERVER SIDE
Ethernet adapter Server Local Area Connection:  (LOCAL LAN)

   IP Address. . . . . . . . . . . . : 192.168.24.10

   Default Gateway . . . . . . . . . :

CLIENT LAN

Client Local Lan ------->  192.168.2.x

Before VPN
IP:  192.168.2.100
Subnet:  255.255.255.0
Gateway:  192.168.2.1
DNS:  Public IP

After VPN

Subnet:  255.255.255.255
Gateway:  169.254.52.157
DNS:  192.168.24.10

Maybe a small detail.. not sure how this comes into play..  

SBS network runs ISA and to browse internet have to set proxy to port 8080.  
I have the VPN connection forwarded to the external network connection and can access local network fine.  

Thanks for the help!

If you setup the connection manually then do the following:
  Go to Network Connections or Connect to ... and Explore All.
  Right click on the VPN connection and click properties
  Networking Tab
  Double click TCP/IP
  Advanced button
  UNCHECK "Use default Gateway on remote network".
  Click OK, OK, OK.

This will eliminate the issue with trying to split the Internet connection on the local computer between the VPN and the actual Internet connection.

As luck would have it..  I found the solution.  Needed to run the connection manager from RWW on the client side instead of setting up VPN manually..  I love SBS more and more everyday!  

Cheers to all.

Phillip,

Thank you for your input.  Yes that did help when I configured the client manually but would lose network connectivity.  I am sure there is something goofy in the network setup.  However, the remote connection client worked beautifully.  Not sure what changed??  Seeing how it is friday night and you offered some help, I will hook you up with some points.

Cheers,

Brian

Thanks for that.

Check and see if the remote IP range is the same as the SBS networks. That can cause some funky situations.

Best to have 192.168.10+.x for your SBS network. Easy to change, just run the change IP wizard from the Server Management Console.
