can't bridge to wlan0

Hi

I have an anoying problem where I can't bridge to a wireless (wlan0) interface. I've tried using two different

versions of vmware server on two different boxes....same story.

My setup:

      Fedora 8 x64 on AMD with RaLink RT2500 (using kernel module or compiled driver)                

Fedora 8 x64 Intel Core 2 duo with PRO/Wireless 3945ABG (standard built in kernel module) 

The wirless works fine on both systems. I can bridge my vmware to the "copper" nics (eth0) and everything

is fine......but for the life of me I am unable to bridge to the wireless interface (wlan0) on either system.

When bridged to the wireless (wlan0) interface, from the guest I can ping the "base" and from the base I can ping and ssh into

the guest .....but from the guest I can't ping my default router(adsl)......the "base" can ping the router and access the internet fine.

I have no firewall no iptables and do not use selinux.

Any ideas?

Thanks
