Ravi,

Folks at Trusted Information Systems created an mbone proxy for the FWTK 
back in 1997. Look for "An MBone Proxy for an Application Gateway Firewall" 
in the FWTK archives.

YOu can find the reference code -- I think this is the same thing -- at
http://www.fwtk.org/fwtk/download/files/contrib/. The file is 
mbone-gw.tar.gz
