OK, when you say "initialize iptables" do you mean that you are using the standard RedHat system V init script called "/etc/rc.d/init.d/iptables" ? If so what is the content of your /etc/sysconfig/iptables? That might be the problem there. When you do an iptables-save what do you see? It doesn't really feel like a kernel/modules related issue, but you lean in that direction, so.... when you type "lsmod" what do you see? On one of my Linux firewalls I see these ipt related modules loaded: ipt_state 1152 25 (autoclean) ipt_MASQUERADE 1824 5 (autoclean) iptable_nat 18452 0 (autoclean) [ipt_MASQUERADE] ip_conntrack 17068 2 (autoclean) [ipt_state ipt_MASQUERADE iptable_nat] iptable_mangle 2272 0 (autoclean) (unused) iptable_filter 2272 0 (autoclean) (unused) ip_tables 11424 7 [ipt_state ipt_MASQUERADE iptable_nat iptable_mangle iptable_filter] Maybe try running "depmod -a" and then reruning the "modprobe ip_tables" On Wed, 2002-11-27 at 06:02, Sam Pointer wrote: > No I didn't custom compile the kernel and the distro is the latest one from > the ftp site at RedHat.
