Cisco 831 VLAN

(sent to superuser.com [1])

Cisco 831 VLAN config.

I'm looking for a simple, fast way to configure a Cisco 831 router to
do VLAN untagging.  I'd like to do something like this:

PORT 1   (E0)  VLAN 1,2,3,4 tagged
PORT 2-4 (E0)  VLAN 2,3,4 untagged
PORT     (E1)  VLAN 1 untagged

All other features should be off.  Just plain and simple untagging.
RTFM pointers also welcome.  I'm a total Cisco newbie.

EDIT: It turns out that the IOS firmware it's running doesn't support
VLAN tagging.  It's apparently possible to upgrade this (the place
where I got it from did that) though it requires an additional
licence.  Makes the box useless for what I need it now..  Switching
back to OpenWRT and a good old WRT-54G.
