Thank you Cedric, I already know this and the bridge is working fine. The problem occurs with the br0 interface through which I cannot reach anything once the $IPTABLES -A INPUT -j DROP is activated. Output is in accept mode and established,related packets are to be accepted - while they are obvisouly not, and this is the problem.
