Adding additional gateways has no effect.

I do have other devices on the local LAN (192.168.0.0) but I can be pretty
much whatever I was IP-wise in this range, with exceptions. (IP's already
addigned to other computers on the local LAN)

I created a virtual interface (eth0:0) and assigned it to 192.168.0.95 so
the pppdserver has 2 separate LAN addresses I "could" assing it to.
192.168.0.133 (D-Link DHCP) and 192.168.0.95 (assigned) all devices on the
local LAN can ping both.

Well, from what I've read on any HowTo's that were even vaguely related, I
have mgetty and pppd working 'as advertised'. When the win98 client is
dialed in and logged on, I can do any normal operation over ppp that you
could when connected to the internet. BUT!! only at/with the pppdserver
machine only. No access to anything beyond the PPPD server. With the
exception that some pings 'beyond' do work. Go figure.

That puts me into trying to figure out why iptables keeps giving me a
"invalid argument" or "invalid target" errors for all my attempts to add a
POSTROUTING chain. See my other thread here titled:
        " iptables - "invalid argument" error ? "

You wouldn't think that hooking this up would be so head-bangingly fun!
