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.
