This all sounds great but exactly how does the "router" (i.e. the Linux
box
with the ppp0 iface configured on it knows which incoming packet is
intended for the original host and which to the Linux box itself, after
all the destination address of ALL incoming packets will be that of the
so-called router with no indication whatsoever as to the host on the LAN
(and this guy has how many??? 20 hosts??)). I went through all the
documentation in NET-2-HOWTO and although it explains exactly how to
obtain and install IP masquerading and the use of the special ver of ipfw,
it DOES'NT say anything about the technical side of things, i.e. , no
answear to my question there.
