Thanks a lot dear..
it worked. but i m still confused that i have the alternative configuration in rc.conf as per guideline here on this page:
http://www.freebsd.org/doc/en/books/handbook/network-bridging.html
it should have worked, but it did not. and here with these commands, it is working.. I am able to get reply to ping

Thanks a lot
