Hi all,

I'm trying to setup an vlan trunk from one of my fxp interfaces (fxp4 in
this case) to an 2950-12 Switch to do vlans for other companies in this
building.

I think I've setup everything right, here's the output from my m0n0wall:

And this is the running-config on the switch:

Have I done something dumb here? Racking my brains for what could be the
cause of it all :) Thought it was just the 3com swithc I was using which was
refusing to let me use vlans, but perhaps it's my config on the m0n0wall?
There are opt interfaces created for it with ip's set, which match the range
that I've set in the vlan ip's.

Any help would be appreciated!
