Hi,
I am having a problem configuring a Cisco 2600 router. The router has 2 ethernet ports and one ADSL WAN port. I have configured the router as a VPN server and when I connect to it over VPN I can ping one of the ethernet ports but not the other. Also, on the ethernet port that I can ping (FE0/0), I can ping the primary IP address but not its secondary IP address.
Below is my router configuration. If anyone could help me with this I would appreciate it,
thanks,
Rebecca

I believe that part of the explanation of your situation is that when you connect over VPN your PC is assigned an address in the ezvpnpool of 10.1.2.240 to 10.1.2.250. This put them in the same subnet as the primary address of FastEthernet0/0. So when the PC attempts to ping the FastEthernet0/0 interface it is in the locally connected subnet and the PC does it easily. To ping FastEthernet0/1 or to ping the seconday address of FastEthernet0/0 is attempting to access a "remote" address and to do that the PC must use its default gateway. And I think that the default gateway on the PCs is not pointing to your router.
I also notice that you have a static route configured for:
ip route 10.1.2.0 255.255.255.0 FastEthernet0/0
I do not understand why you have this static route. The connected subnet should be in the routing table anyway.
Check the gateway issue and let us know what you find.
