Where did your gif0 interface come from? I've added it using  
'ifconfig gif0 create', but when I try to add it to the bridge I'm  
getting the following response:

[~] bob at spike> ifconfig bridge0 addm gif0
ifconfig: BRDGADD gif0: Operation not permitted

I've noticed that in /var/log/messages it said that the mtu didn't  
match, so I've solved that an put both mtu's to 1500. However, the  
message still pops up when trying to add gif0 to the bridge.

Does anyone have clues as to how this can be done?
