I get this: fw root # insmod ip_tables Using /lib/modules/2.4.20-hardened-r2/kernel/net/ipv4/netfilter/ip_tables.o /lib/modules/2.4.20-hardened-r2/kernel/net/ipv4/netfilter/ip_tables.o: unresolved symbol nf_unregister_sockopt /lib/modules/2.4.20-hardened-r2/kernel/net/ipv4/netfilter/ip_tables.o: unresolved symbol nf_register_sockopt fw root # When trying to load the ip_tables.o module and it causes problems on down the line with other modules not loading. Anyone have any idea how to fix this? I'm running kernel 2.4.20. I have everything under the netfilter section marked as a module except for realm match support (because the kernel fails to compile with it). Thanks, Robert
