again ..... how is one supposed to know stuff like this ??

hmmm .... well since the dialog box pops up asking for some IP number to be
inserted in a field titled "netmask" in every distribution I have seen, I
wondered what it was there for .... I know its there in other operating
systems too but like I've found many times, *nix does stuff differently
and as far as I knew it just maybe it could have been an issue that needed
to be addressed

tell your end how to reach the other end of the link.

OK ..... so I guess you mean the LAN gateway box is one "peer" and the ISP
or equivalent is the other "peer" ??

I'm trying to figure what you mean exactly ... I assume "Your end of the PPP
link" is the ppp0 on the LAN gateway box, and "the other address" is the
eth0 on the same box ??

The rest I'll try to absorb gradually by sketching it out on paper  .....
however I don't need to mess with firewalls or DHCP immediately if they
aren't strictly essential to basic functionality so is there any other
reason I need to be concerned with that stuff ??
