The bridge is not necessary. If you're trying to make all the traffic 
traverse the wireless network, you'll have to change the default gateway 
on the client. Otherwise the traffic will traverse bge0 as indicated in 
the client routing table. Otherwise, I would examine the firewall. 
Change it to allow all traffic and see if that makes a difference. 
Verify that your nat configuration is correct.
