The iproute2 patch for the 2.6 series is differnt then the 2.4 series. Make
sure you have a recent iproute2 patch. The command syntax has changed as
well for the 2.6 series:
ip route add 10.100.0.4/32 via 10.100.0.4 spec_nh 0x8847 <key>
I'm not sure of the iptables problem, but others have reported issues with
the new iptables. I will have to look into it.
