By my opinion problem is in behevior of software listening 10.0.0.1:80 it must be not standart proxy (like squid) standart proxy listens one address and got requests with full URL like: GET http://www.somwhere.net/path/here.html HTTP/1.0 but your browser may send requests without protocol and hostname like: GET /path/here.html HTTP/1.0 so software, listening 10.0.0.1:80 must got destanation IP from request and insert it in proxy requset you can play with telnet to chechk how it works standart software for this need present in ports and called tranproxy but it designed to work with ipfilter, not IPFW -- TSB Russian Express, Moscow Vladimir B.
