[gentoo-user] iptables

["John Dangler" <jdangler@atlantic.net>]

I emerged firestarter (during which I got iptables), and forgot that I
didn't have iptables emerged prior.  I went into the kernel and selected (as
the doc I found suggests) all of the options as modules under iptables. (The
doc also says that if they are compiled as modules, I didn't need to
reboot).
I did add iptables to /etc/modules.autoload.d/kernel-2.6 (for subsequent
rebooting).

modprobe ip_tables results in:
FATAL: Error inserting ip_tables
(/lib/modules/2.6.12-gentoo-r9/kernel/net/ipv4/netfilter/ip_tables.ko):
Unknown symbol in module, or unknown parameter.

dmesg produces - 
ip_tables: disagrees about version of symbol skb_copy_files
ip_tables: Unknow symbol skb_copy_bits
ip_tables: Unknown symbol nf_register_sockopt
ip_tables: ip_tables: Unknown symbol nf_unregister_sockopt
ip_tables: Unknown symbol nf_unregister_sockopt

(I just found another doc that says to ONLY modprobe IF you haven't built
this as a module)
DOH!

I went back into the kernel config and removed all but the essential options
for iptables... (just iptables module) and rebuilt the kernel

A reboot (aside from losing my wireless), produced an error on boot loading
iptables.
no other text in dmesg points to the problem.
