I am new in linux world,basically I'm using red hat 9 kernel 2.4.20-8. I need to build a trusted gateway. my linux box will be the gateway for several machine PCs to go to the desired server. there will be several subnets under the linux box, I've already assigned static IPs for the PCs . Now my problem is I only need 2 PCs from each subnets to connect to certain servers, and those 2 PCs can only have transaction(open) to the specified servers, for others it will drop(firewalled). for other PCs, they can't log on to the outside world. should I use only iptable rules or with the help of squid(ACL) as well ? please add up the commands as well. Thanks. __________________________________ Discover Yahoo! Use Yahoo! to plan a weekend, have fun online and more.
