Hi Dave, Lot of thanks for your detail advice. As suggested Shorewall will suit my application. The three boxes are located in the same house and can be connected via a crossover cable. RH9.0 will be the server providing Internet access to other 2 boxes. Protection with firewall is necessary.

I am interested to test this simple setup linking 2 RH boxes via a **CROSSOVER** cable. RH9.0 box (eth0 connected to xDSL-broadband) -Setup eth1 as ethernet connection -Configure Network Settings -Check "Statically set IP address" Address: 192.168.1.1 Subnet Mask: 255.255.255.255 Default Gateway Address (blank) RH8.0 box -Setup eth0 as ethernet connection -Configure Network Settings -Check "Statically set IP address Address: (blank) Subnet Mask: (blank) Default Gateway Address 192.168.1.1 If I am wrong please correct me. > OpenVPN is a powerful tool for creating secure tunnels across an untrusted > network, such as the internet.

Interesting. I will go through the document mentioned later. Will OpenVPN be installed on all boxes in the network sharing data, i.e. no server nor client?
