Hi all,

I'm currently running ipfw+natd to do ip masquerading and address
redirection. I am now trying to setup transparant proxying, but don't seem
to be having too much luck.

proxy_rule              tcp encode_ip_hdr port 80 server 192.168.62.1:8080

Above is the line from natd.conf, but it appears to be having no effect. One
thing I'm wondering... I was having a problem earlier with the
redirect_address, and the reason was because I am using interface rl0 for
natd which is my public ip address and I was testing the redirect from a box
on the local network which routes through rl1. Because my requests weren't
going THROUGH rl0, the redirect wasn't and doesn't work internally. Could
this have something to do with the transparant proxying not working, or is
my syntax incorrect?

Cheers

Mike
