[TriLUG] iptables - sometimes stops working

[Jon Carnes]

I had a similar problem once.  It wasn't IPTables but the network driver
I was using for the NICs.  The driver worked fine for one NIC but not
two.  I replaced one of the network cards with a different type (and
different driver) and all worked happily every after.
