The CV860A (at least the realtek version) DOES work with a vlan.

The procedure I used:
Add vlan, host is opt1, id is 101
add interface, we now have opt2.
Give opt2 an ip address/range
add a rule to wan to allow ingoing packets destined for that range
add a rule to opt2 to allow outgoing traffic
on the switch - we used a suspiciously poorly documented planet switch -
set:
port 1..23 with vlan id 101..123
create 23 groups so all 23 ports share a group with port 24 (members are 1
untagged ,24 tagged)
plug opt1 into port 24

After you've worn out the mouse you'll be looking for a faster box to run
m0n0 on, since the webgui is a tad slow.

It's a pity m0n0 won't bridge more than two interfaces. I would like to have
a setup where the m0n0 was just a very smart switch.
That would allow me to have 47 clients, with 47 public, routable ips, and
ensure they can't transmit packets with each other's IP address as source.
