Please can someone help with a VPN question. When I create a tunnel interface and bind it to an ethernet interface, can the ethernet interface only be used for the tunnel only or can VPN traffic be routed to the tunnel and normal traffice passed straight thru.
Regards

Hi Bryan,
you can use the ethernet interface for both.
You habe to make your routing entries for the Ethernet and for the tunnel.

Excellent, thanks for the information. Are you able to point me to Cisco's website for any examples of this as this would be most appreciated.

Hi, I was also need to VPN to a remote site while maintaining internet access for the local network. Great example by the way!
Let me see if I am correct in this hack of your example.
I want to tunnel internal LAN 192.168.1.1.
To remote IP xxx.225.137.113.
From here xxx.11.70.9
My config:
interface Tunnel70
ip address xx.11.70.9 255.255.255.248
tunnel source Ethernet0/0
tunnel destination 66.225.137.113
tunnel mode ipip
!
!
interface Ethernet0/0
description Exodus LAN
ip address 192.168.1.1 255.255.255.0
!
interface Serial0/0
description P2P E10
ip address xxx.11.70.9 255.255.255.248
service-module t1 clock source internal
!
ip http server
ip classless
ip route 0.0.0.0 0.0.0.0 192.168.1.1
ip route xxx.225.137.113 255.255.255.0 Tunnel70
TIA for any pointers...
