Hi there I've got ADSL ppp0 facing the net, at x.x.x.47 [as part of a x.x.x.46/29 subnet], and I want to do static NAT for hosts 48,49 and 50. I have a quick question, and my Ziegler book is at home at the moment. Back in the days when I worked with Checkpoint, I would have had to have ARPed 48, 49 and 50 onto the external interface via the operating system, for the one-to-one static NAT to work. Do I need to ARP the IP addresses onto ppp0 under Linux / iptables also? This is a Linux RH9 / ADSL WAN connection / iptables situation. Thanks in advance for any answers!
