Wireless Networking and multiple SSIDs

So I got my WRT54G v3 router back from the friend that I lent it to. J’s been bugging me to get her DS Lite on the Internet, so she can trade Pokemon (*sigh*). Anyway, having done some research prior to this, I had determined that it’s possible to do multiple SSIDs when using a third party firmware called DD-WRT when using at least v24 (which is still in RC status).

First step: install the newest Linksys firmware. Then I install the mini generic DD-WRT firmware. From there, it’s on to the the standard firmware. So, I create a virtual wireless interface, which seems to have done so fine. Then I add the following commands:

startup:

fconfig br0:0 down
brctl addbr br1
ifconfig br1 192.168.21.254 netmask 255.255.255.0 promisc up
brctl delif br0 wl0.1
brctl addif br1 wl0.1
killall dnsmasq
dnsmasq --conf-file=/tmp/dnsmasq.conf

dnsmasq:

interface=br1
dhcp-range=br1,192.168.21.1,192.168.21.149,255.255.255.0,1h
dhcp-authoritative
dhcp-option=br1,3,192.168.21.254

firewall:

iptables -I INPUT 9 -i br1 -m state --state NEW -j logaccept
iptables -I FORWARD -i br1 -o vlan1 -j ACCEPT

And the net effect of all this? Nada. Can’t reach the second SSID. Nothing works. Try the RC7 pre-release. Still fail. Trying to get an answer from the forums, but I this isn’t solved by Saturday, I’m sticking Tomato on the box, and just using two routers to get the DS Lite on.
