Here is an description what I want do do: Server1: -eth0 10.3.1.4 -ppp0 x.x.x.x ServerPROXY: -etho 10.3.1.8 -ppp0 y.y.y.y Server1 has set FORWARD in iptables for Telnet i FTP services ( so users from LAN are able to connect those services in the internet ) ServerPROXY has Squid service (PROXY for http only) All of the hosts in LAN must have set gaytway 10.3.1.4 (eth0 Server1) What should I do to redirect all connection from LAN on port 80 to serverPROXY 10.3.1.8:8080 ? I heard that POSTROUTING or PREROUTING rule need to be used Any suggestions ? Someone told me that it might be necessery to compile some additional options in kernel (my current kernel is 2.4.31 - regular kernel from Slackware 10.2 ) Any ideas how to slove that ?
