Doublecheck that. I don't think a tun interface can participate in a 
bridge, because tun is TCP/IP, layer 3, whereas bridging occurs at 
layer 2, Ethernet. The same driver (tun) can provide tap (virtual 
Ethernet) devices as well.

Then you most likely are using rules which prevent the bridge from 
working! This is not a "smart question" (see the well-known catb.org 
link) because you have given us nothing to work with.
