trunk0 does not work as expected

[gosha]

Hello,
at the end, posting in misc, I've found out that the problem with iwn hanging is very common, at least with the 5100 nic. I solved it with a script that brings the nic down and up every time it detects there's no connection. Hopefully it will be solved for 4.6 (I don't think I'm very fit to run -current).

Now the problem with trunk0:
actually I posted this already but in a thread with another title, so I think it's better to repeat it here, since it's a problem only with trunk.
The problem is, wireless works just fine, and if I plug in the ethernet cable trunk switches to it, but it has no connection.
What could the reason be?
Here are my settings:

$ cat hostname.em0
up

$ cat hostname.iwn0 
up chan 6 nwid mylan wpa wpapsk mykey

$ cat hostname.trunk0 
trunkproto failover trunkport em0 trunkport iwn0 192.168.1.102 netmask 255.255.255.0
