Transparent web redirection

["Doug Clements" <dclements@linkline.com>]

Greetings,
   I was wondering if anyone has been successful in setting up transparent
web redirection using a bridge in openbsd. I'd like to basically firewall
everything but web traffic, which gets routed to a Cacheflow. Has anyone
ever done this with a bridge? I think I can do this with ipnat as well, but
will ipnat do redirects without actually doing any NAT?

Does anyone have a preferred way of doing this?

Thanks for any help or pointers you all can give...
