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.
