I'm trying to set up the following solution but having trouble working it out, so hopefully someone can help

I have a DSL line wth a BT DSL router/modem- this is working fine, if i attach a pc to one of the ports it picks up an IP (192.168.1.x/24) and have an internet connection. DSL router/modem has an internal address of the gateway being

I have attached a patch from this DSL router/modem to SWITCH1 port 3

port 2 of SWITCH1 is a attached to a PC




port 1 of SWITCH1 is atached to F0/1 of Router1 (Trunk)

With the dunp of configs attached I can ping from the PC the & but cannot get a internet connection.

Just so you know I'm trying this setup because I want to eventually setup a LAN-LAN VPN tunnel from the Cisco 1700 router.

I have this problem too.

But your router doesn't know about, so you need to tell it how to get there.

Use the ip route command to accomplish that and set your gateway of last resort.

ip route
