I have been running an older version of iptables 1.2.2 under 2.4.9. I have been unable to patch this kernel to iptables 1.2.7a, so I downloaded the 2.4.19 source. I patched this kernel fine, but whether I compile iptables as modules or right into the kernel, when I boot into 2.4.19, I get the following errors on most of my rules: iptable: Invalid argument When I reboot into 2.4.9, everything works. I have upgraded the iptables binary to 1.2.7a, and it works under 2.4.9. Am I missing something? -- Aaron Clausen
