I have seen that "open rule" is insecure, and i wouldn't like to use it... i want to continue trying to find the closed port, with this policy... there must be something somewhere... so... i will continue bothering. sorry i am a beginner, here are some conversations in the past that weren't submitted to the group. ------------------ Proxy is an cache server. If u dont need , not use. If u want to use proxy for caching web traffic and force this traffic throught proxy,u can do that with fwd option in ipfw example: ipfw fwd $ip_proxy,$port_proxy tcp from not me to any 80 in via $private_interface
This not affect in any way functionality for mail aplication (that work in case of pop3 with 25 respectively 110 ports). If u acces mail via web, this work well with proxy. If still have problem, i'm sure is because configuration of proxy (think use squid). I this case u need some options to permit "connect" method. I dont remember now how look exactly. ---------------------- I have done this.. at the command line, ipfw add fwd 172.25.1.5 <http://172.25.1.5/>,80 tcp from not me to any 80 in via vr0 04200 fwd 172.25.1.5 <http://172.25.1.5/>,80 tcp from not me to any 80 in recv vr0 also ipfw add fwd 172.2X.X.X,80 tcp from 17X.XX.XX.0/24 to any 80 in via vr0 nothing happens.. i do see traffic, but very little.. this should refresh it ? i mean, this rule is active immediately? because i can not do attachments yet.. not even showing my message list in yahoo..
