Cisco VPN killing MSN Messanger and Voice Connection

I have a Cisco VPN and when our outside sales people connect to the VPN they lose there MSN Messenger there Yahoo messenger and a company Voice server that we host.  I tried to tell it to use the Local LAN settings in the client set up but still not working.  Any ideas?

When the Cisco VPN clients connects it will cut off all other network access to the machine, this is intentional and i'm not sure if you can change that or not.  The only access will be to the cisco vpn server and the network you are connecting to.

  You'll need to allow less-secure "split-tunneling" for the VPN clients - this will let them access the Internet directly from their laptop & also access the internal corporate network via VPN.

If this is a Cisco router or PIX 6.x series, please post your complete "sanitized" config (passwords removed, public IPs masked like so: x.x.x.83) & I can provide changes to enable split-tunneling.  Or you can also see a brief example for a PIX in the following post:
