Split-tunnel with no internet access

[bkimble]

We have someone running a split-tunnel client vpn connection to our corporate network from behind a customer's network. This person is able to access everything on our corporate network with no problem. Unfortunately, they are NOT able to access the public internet.

Since we are using split-tunnel, the traffic to our corporate network should go throught the tunnel and the rest should go though the customer's LAN. I don't really know where to start troubleshooting this.

Any help will be very much appreciated.

Thanks,

I would suggest to try have the client do a trace route from their pc after they connect with the VPN client to "see" where its getting droped. Trace route to a public IP address ex: 4.2.2.2. If you can ping that IP address after the VPN connection is established perhaps the problem is with their dns/def gateway.

Well it appears to be a dns issue. I had him browse to google's IP address and the page came up fine. When I had him try ipconfig /all he got an error message saying that dns information couldn't be found.

I had him connect to our backup vpn concentrator and everything is working fine. I connected through our internal lan to the primary concentrator and I had the same problem the user did... Corporate networks are available and public are not. I also got the dns error when I ran ipconfig.

I suppose I'll have to compare the configs on the two concentrators and see what's different.

thanks for the response!
