Hi guys, Thanx for all your suggestions, but i have bad news. The rules you guys are suggesting make a lot of sense to me but they don't work. My hosts still cannot surf the net. This rule: iptables -t nat -A POSTROUTING -o ppp0 -j SNAT --to-source <ip-of-ppp0> is another form for the masquerade rule: iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE Using either of these two rules my hosts can access internet, but i still have the problem of the load balancing. Some ppp links are used more than others in situations such as loading the same web page in four different browsers. As soon as i add the "nth" rules to the mangle table my browsers stop working, they just can contact the web servers and eventually they time out. I'm not sure if by adding any rule to my mangle table the browsers stop, but at least they stop when i add your suggestions to the mangle table. Any other ideas, suggestions, tips?? all are very welcome... Thanx to all, i really appreacite all your time and interest....
