Re: netfilter before routing for local outgoing packets ?

[DALive Editor <dalive@xxxxxxxxxxxxx>]

Hello sir....I'm but a humble rookie. Yet, i recently, and very proudly 
compiled my first kernel. And this is a feature/option selectable in the 
kernel configuration, called "NAT of locak connections", under 
Networking Options > Networking Configuration. By the way, that was 
kernel 2.4.22.

Someone correct me if I'm wrong please.
Peace.
