Question : Problem: VPN Tunnel is connected, but traffic ignores it...

I have 2 cisco PIX 501's, one wiht static IP the other dynamic.

VPN Server is on the static end, but it is at the remote site... called Red. I can get to the internet, but it I try to ping

10.10.10.1  ---- Cisco PIX 501 --- Dynamic IP  <------------->50.50.50.50 (Static IP) ---- Cisco PIX 501 ------ 10.10.20.1

The VPN Tunnle light is lit... but I cannot ping or reach any of the 10.10.10.0 addresses (behind blue) where the W2K3 Server (10.10.10.10) is and it is the Domain Controller / DNS. I think there is probably an issue with the Split tunnel.. but do not really know. I do see one error in the "vpngroup unityclient dns-server 10.10.10.10 192.168.1.1". The 192.168 address is left over from testing and should be 151.198.0.39, but I do not think that will fix it.

Here is the setup for Red PIX

Answer : Problem: VPN Tunnel is connected, but traffic ignores it...

tgreendyk,

Check the address ranges used on all three user networks (yours and the two other users). Also check the IP address range used on your VPN and intranet.

Use the IPCONFIG command to display the information for each system.

If you have the same IP address range on both sides of the tunnel, you will not be able to access resources. The tunnel will establish because it is using the public IP addresses.
