These are some files referenced by my pages in the TuxScreen wiki on building
a firewall/router out of a tuxscreen.

S60iptables -- sysvinit startup script, functionally analogous to Debian's
iptables*patch -- patches the iptables build to disable IPv6 (not in uClibc)
iptables.mk -- makefile to do the build, goes in buildroot-tux/make/
