I'm looking for some urgent help please.
I have a Cisco 1901 router with 2 onboard Gigabit Ethernet ports that are configured as a BVI due to an unusual config with the ISP (it works!).
I also need to route/NAT to from 2 or 3 other subnets and requested my reseller to provide a 4 port HWIC which they did.
I tried to apply ip addressing to the FastEthernet ports only to receive a message stating it wasn't possible on a Layer 2 port.
I therefore created a vlan and assigned it an ip address and subnet mask from a subnet I wished to route traffic through. I assigned the vlan to the Layer 2 FastEthernet port but cannot ping or route through it.
Is this even possible or am I banging my head against a very solid wall.
