My WAN interface is not reacheable (CISCO 1811 router).

By mkdpeter ·
I have two WAN Interfaces :
I use the f1 for my all vlans (16). Internally, all things work. All my vlans are reacheables and can ping my internals LAN subinterfaces (f1.1, f1.2, etc.).

But my WAN still stay unreacheable. Here is it config :

# show interface
