[2008.12] Anyone get iptables working?

[Nick Van Fossen]

Ahh dang I should have checked my e-mail again earlier.  I followed Timo's suggestion to rebuild from source, and that worked like a charm.  But your fix would have saved me a bit of time.  If anyone wants an ipk of iptables v1.4.2 let me know :)

Thanks everyone
