The gateway needs (at least) two network interfaces: one connected to the internet and one connected to your private network. Why the alias? If you assign aliases to a network interface...it isn't connected to more networks. > my input chain is using ACCEPT as the default policy and no rules. > the output chain's policy is ACCEPT, no rules. > the forward chains's policy is DENY and it has one rule: > MASQ all protocols source 192.68.1.0/24 destination 0.0.0.0/0 ports n/a ^ typo? > the Linux box responds when I ping it from a client (ping 192.168.1.1) > and also the Linux can reach all the clients. Ok. > But the clients can get out to the internet!. I guess here is a 'not' missing. ;) Do the clients have the default gateway set to your gateway? moritz -- Moritz Schulte <[EMAIL PROTECTED]> http://hp9001.fh-bielefeld.de/~moritz/ Debian/GNU supporter - http://www.debian.org/ http://www.gnu.org GPG fingerprint = 3A14 3923 15BE FD57 FC06 B501 0841 2D7B 6F98 4199
