Linux bridges can have IP addresses, and in fact is a must if you want to run a proxy there but it is not the point.

ip forwarding should not be needed in a bsd bridge either.. a bridge is by definition forwarding Ethernet frames, not IP forwarding.
Please do not confuse bridge with routing or proxy-arp. a bridge operates at the Ethernet layer and is not related to IP forwarding while routing (including proxy-arp) operates at the IP layer and needs IP forwarding.
u are very right.
i know we are pretty off topic but let me tell u mine point.becoz u are not understanding me well.
which is due to unclear question.
consider a example which i considered in this problem.
a machine with 2 ethernet cards (eth0,eth1) operating as bridge whereas its 1 ethernet interface(eth1) has ip address and squid is running on it, now that machine is connected to internet through ppp0 (as pp0 is not part of bridge) . ipforwarding is enabled to communicate between eth1 and ppp0.
a machine acting as a bridge and router at the same time. which i have done in openbsd.
