First installation of gentoo, used cd's 1 & 2, stage 3 tarball plus the GRP. Gentoo-sources and genkernel to build the initial kernel. Iptables weren't in the kernel. iptables package emerged OK.
I've now tried multiple times to enable iptables, using configurations from my debian and mandrake set-ups which work fine on the same box. I cannot get the exact same options - can't find CONFIG_NF_NAT_NEEDED anywhere during make menuconfig on gentoo. That aside, the networking options are identical, the kernel builds fine (make clean && make bzImage && make modules && make modules_install) and boots without any obvious problem.
However, modprobe ip_tables gives the errors "unresolved symbol nf_register_sockopt" and "unresolved symbol nf_unregister_sockopt".
I've googled around but found nothing useful, perhaps because several servers time out. 3 questions:
1. Is there some obvious option I need to build in here, perhaps the NF_NAT_NEEDED thing I can't find?
2. Am I missing out some crucial stage in getting the modules inserted?
3. Or what?
I won't claim to be an expert user, but I have iptables working on my server. I don't think the default genkernel confiigures the kernel complile for the iptables modules. If you want to use genkernel, you have to do "genkernel --config" and then enable the modules manually when you get to the makemenuconfig stage. Incidentally, I use the xfs-sources kernel, but I would assume this is true of the gentoo-sources kernel also.
