Cisco VPN Client can't access internet when connected

By congers ·
Here is the problem. When I connect to some of the companies that I consult for using the cisco vpn client I can use the internet. They have split tunneling turned off. So I can fix this by enabling split tunneling. I also have allow local LAN on but that doesn't make a differece.

SOOOO, I am wondering if I have 2 NIC cards in the machine and I use 1 to connect to the VPN can I use the other to connect to the internet? The problem being I have one DSL router that controls my work. It is the DHCP and my way to the outside world. I was thinking that if I set up 1 NIC card (subnet A 192.168.1.2 mask 255.255.0.0 statically set with gateway of 192.168.2.2 (Dlink Game Lounger 4300 and DNS statically set to what the router has) and the other NIC as subnet B (192.168.2.143 mask 255.255.255.0 dynamically given out by the DHCP)

Now the DLink Game Lounger has 2 routes added to the routing table:

192.168.1.2 (NIC 1 subnet A) mask 255.255.0.0 gateway 192.168.2.2 (DLINK Router IP)

192.168.1.0 (NIC 1 subnet A) mask 255.255.0.0
gateway 0.0.0.0

I am running windows XP and I have IPForwarding enabled.

I haven't been able to connect to VPN and get to the internet. Any help would be greatly appreciated.

Thanks,
Susan

make your internet GW the default GW and add static route to your VPN

Try
route -p add xx.xx.xx.xx mask 255.X.X.X YY.YY.YY.YY metric N
when:
xx.xx.xx.xx = destination IP
255.X.X.X = destination Subnet mask
YY.YY.YY.YY = the gateway
N = The metric "the cost of gateway"

Manually change the routing table

It seems the routing table as defined in your cisco connection prevents you from accessing the internet..

In windows xp, you can change that manually as follows:
route delete 0.0.0.0
route add 0.0.0.0 mask 0.0.0.0 10.101.24.1
route add 10.160.121.0 mask 255.255.255.0 10.160.136.47

where:
10.101.24.1 ==> is my internet gateway as seen in ipconfig
10.160.121.0 ==> is the subnet of the servers I want to access through VPN
10.160.136.47 ==> is the cisco client ip as seen in vpn statistics
