WAN and dialup simultaneous connections

[Guest]

My Win XP Pro PC is connected to a corp WAN. I'm trying to use PPP dialup to
connect to a remote PC that has no WAN connectivity. When dialup completes,
WAN connection is disconnected, cannot ping core router on WAN side but can
ping router on local LAN side. XP supports multiple connections. Why is
this happening?

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.
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.

Robert, thank you for the information. I did find the gateway setting in the
TCPIP properties of the dialup connection and will try this tomorrow to see
if it works. Thanks again.
