Have you sent the patch yet? I'd like to include it in the next HOWTO.

Thanks Joe

Hi Joe,

I did send both patches to the list, one for the kernel and one for ipvsadm. (both marked "PATCH x/2 inlining")
If necessairy I can resent them.

But I do need some feedback on some concepts in the patches. (especially the kernel patch)

I did some rather intrusive work, providing a new netfilter hook for LVS on NF_FORWARD. I'm not sure if that will not have any adverse effects on existing setups.

Main differences/concepts:
Normal LVS: Netfilter hook on input only
My patch: Extra Netfilter hook on forward.

Normal LVS: three directors: TUN, NAT, and direct routing.
My patch: Extra director: Reinject (Change skb->dst and return packet to normal routing via NF_ACCEPT, only effective on forwarding hook)

Greetings,
Ludo.
