I've been trying to replace my ISP router with a 1941 ISR and don't wan't to use the ISP router as a bridge.
I've successfully set up the interface and trunk and able to ping the public side from my router directly, however while all private clients are getting DHCP assigned IP's as expected and internal is fine, I'm totally stuck on getting the local machines talking...
At the moment I'm just looking to get the basic functionality sorted:
As can see, the interface is all good:
