Unresolved Symbols

[Rob Hill]

I tried insmod first, I should have included that info as well in the first
message.

root@guardian:~# insmod iptable_nat
Using /lib/modules/2.3.99-pre9/ipv4/iptable_nat.o
/lib/modules/2.3.99-pre9/ipv4/iptable_nat.o: unresolved symbol
ipt_unregister_table
/lib/modules/2.3.99-pre9/ipv4/iptable_nat.o: unresolved symbol ipt_do_table
/lib/modules/2.3.99-pre9/ipv4/iptable_nat.o: unresolved symbol
ipt_unregister_target
/lib/modules/2.3.99-pre9/ipv4/iptable_nat.o: unresolved symbol
ipt_register_table
/lib/modules/2.3.99-pre9/ipv4/iptable_nat.o: unresolved symbol
ipt_register_target
root@guardian:~#
