Hello, When I add interfaces to the bridge *after* I have "tcpdump -n -i br0" running on the bridge, my tcpdump don't see any communication. If I kill tcpdump and re-execute it *after* I added the interface to the bridge, it works just fine. The same behavior happens with my DHCP server (which listens only on my bridge interface); I need to re-execute (reset) it after I add the interface to the bridge. Is that normal ? Why does it happen ? What should I do ? It's a little awkward to reset my DHCP server every time I add a new interface to the bridge.. Thanks, Sabhe
