I thought so. The device was assigned an IP. It has a menu where I could 
also see that it was assigned a DNS server and also a default router. And 
the wireless router / DHCP server also has a DNS server which has the new 
hostname as provided by the device.

But now I am thinking that was from old settings from when the device was 
plugged directly to the router in the other room. tcpdump doesn't show the 
dhcp going both ways. I can see in my tpcdump output when the device is 
configured with its previous IP.

And from my NetBSD system I can ping the device. (That's how I saw the 
hostname because of reverse lookup. The hostname includes SIP -- the 
device is a phone.)

I found some emails from this on pkgsrc-users in Sept. 2007. I read that 
maybe you can't bridge with any of NetBSD's wireless drivers -- but 
bridge(4) manpage clearly mentions 802.11 and wireless. Also I read that I 
need a card that supports having as many associations to the AP as 
required. I don't know if my ral0 does. It is:

ral0 at uhub5 port 1
ral0: Cisco-Linksys Wireless-G USB Network Adapter, rev 2.00/0.04, addr 2
ral0: MAC/BBP RT2570 (rev 0x03), RF RT2526
ral0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
ral0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 
24Mbps 36Mbps 48Mbps 54Mbps


The ral0 is working for DHCP also. I assign ral0's via dhclient and have 
done that for 1.5 years.

How do I know if my ral0 will allow multiple associations?
