I have a 2811 router with the 9port HWIC installed. I am trying to use the Fa0/0 port as an uplink to my corporate LAN for the VLAN that is configured on the HWIC. I have tried adding an IP directly to the Fa port and also tried creating dot1q subinterfaces on the Fa port with no luck. When I did this the local IPs could ping each other but no connection to the corporate LAN could be established. I resorted to using one of the HWIC ports as the uplink using the config below. How can I setup the Fa port as the uplink so I can free up the HWIC port I am currently using?
Thanks,
Diego

You cannot connect 9port HWIC to you internal LAN through onboard F0/0,F0/1 ports..
"interface Vlan100" and
"interface F0/0.100
enacap dot1q 100"
is not the same thing..

How do you distinguish between them and what's the use of "interface Vlan" command?

I don't understand where you are going with that. Would you be so kind as to give more detail?
Thanks,

my english is not perfect :))
you have a router with two onboard ports (F0/0,F0/1) and one virtual port for HWIC access. The virtual port is a trunk to your HWIC. To access vlan 200 on HWIC you must create "interface vlan200".
But there is no briging between the virtual port and F0/0,F0/1.
So you can connect them each other only by routing.

I believe that is the case with hwics , they are basically a standalone switch inserted into a router chassis .

I think I understand now. Thank you very much.
