You can do that with the freeman firmware too.  It's a matter of using
vconfig or something.  I have done it before.

With openwrt it is very easy to define the vlan's in the nvram and then
get the ifup command to automatically set things up.  Basically the
wrt54g has a 5-port ethernet switch device, collectively known as
"eth0."  Using vlan tagging on the ethernet packets, you can group the
ports anyway you want.

I'm planning to completely turn off bridging between my ports and do
straight routing with vlans (and firewall rules between each vlan).

I just barely discovered that with a couple of simple nvram settings and
the nas ipkg, I can turn on WPA, which is nice.  Anyway, I don't miss
the web interface at all.
