Hi there,

I have been reading about NATD and have a question to ask:

We currently have a FreeBSD server on our internal LAN, where we use internal IP addresses (192.168.xxx.xxx).  We all connect via a proxy running on the server to the internet which has TWO dial up PPP connections (ppp0 and ppp1).

At the moment, routing is performed every second and is basically switched from ppp0<-->ppp1 to spread out traffic evenly.  (Ie. the default route is changed).  This works well for WWW traffic.

Is there any way to 'wrap' packets in a header and give them the IP address of the interface that they are currently being sent out of - does natd do this?  I dont want to route all the LAN traffic through the server, just the server traffic itself, so i dont know if natd is the answer, but I have a suspicion it lies in there somewhere with IP masquerading or IP firewalling or IP divert..?

Any help would be *greatly* appreciated..
