VPN with a Wireless network card doesn't setup routing table properly.
1. for the security reason, some company vpn ip range and LAN ip range are
different. for example, our vpn ip is 192.168.1.0 and LAN is 10.0.0.0, if we don't use default gateway on remote network, we can't browse the LAN. 2. both metrics are 1 that is OK. the router will know if you go 10.0.0.0, the router will point you to 10.1.10.113; and others will go to 192.0.2.2.

Robert, thank you for your help, that did the trick. The routing table shows that all 10.x.x.x address are sent to the VPN connection 10.1.10.113. Any brief reasons why this works. The description says "When checked, data that cannot be sent on the local network is forwarded to the dial-up network.". Sounds like you would want this option checked. Also, why isn't the 10.x.x.x traffic sent to the 192.0.2.1 gateway when the first entry has the same metric and starts with 0.0.0.0? Here's the routing table after that is checked: ================================================== ========================= Interface List 0x1 ...........................

When I VPN into my office network from home I cannot access any remote network resources via my wireless network card. But if I VPN using my standard built-in network card I can access resources. My local network is addressed with 192.0.2.x addresses and the remote office network addressed with 10.1.10.x. When I examine the routing table it appears that the Interface Metric is the same for both the remote gateway and the local gateway. Whereas when the standard network card is used the metric for the local gateway is set to a higher value. So it appears that with the Wireless card traffic for the 10.1.10.x addresses are routed locally. Is this correct interpretation of the routing tables? And how can I resolve this problem. I tried changing the initial metric of the wireless card to 20, but it gets reset when the VPN connection is established. Any assistance greatly appreciated.
