Can't access the Internet while using VPN
Symptom: after establishing a VPN connection, you may not be able to access
the Internet because the VPN takes over your existing connection and all
traffic to use the VPN default gateway on the remote network. The remote
network may not allow VPN clients to access the Internet via their gateway.
Resolutions:
1) If you don't need to access the entire VPN resources, disable the "use
default gateway on remote network" option in the properties of the VPN
connection. To do that, go to VPN
Connection->Properties->Network->TCP/IP->Properties->Advanced-, uncheck
"Use default gateway on Remote Network".
2) Edit route table manually if you know how to or check routing page on
this web site.
3) For the security reason, some firewall/routers like Cisco PIX do not
allow access the Internet after establishing the VPN and you cannot modify
the routing table. You may setup split-tunnel.
