Hello All, After N iterations of compiling kernel, installing iptables, applying patch-o-matic... the following command in a script from NAT HOWTO failed to execute iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source XXX.XXX.XXX.XXX with an error "iptables: Invalid argument" I suspect, that an argument is XXX.XXX.XXX.XXX yesterday everything was fine (even more - it used to work with iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE but now to the command -j MASQUERADE it says - "iptables: Invalid argument") ok I changed -j MASQUERADE to -j SNAT - it demanded --to-source I issued the above and got stuck on that Anybody has a clue on it? Debian 3.0 iptables v1.2.9 kernel 2.4.22 I even tryed to reboot with an old kernel - the result is the same. Please help -- Oleg mailto:savostyanov@xxxxxxxxxxxxxxxxxxxxx
