"Unnumbered interfaces" (this is Cisco's terminology if I am right) are
Point-to-Point interfaces under Linux.

If I understood you right, 1 is attached to your ISP by Ethernet, so let's
assume it's eth0 interface is configured like this:
  ifconfig eth0 netmask broadcast
  route add -net
  route add default gw

Your LAN has it's own Class C subnet, say eth0 on 2 is configured like
  ifconfig eth0 netmask broadcast
  route add -net

In short, your ISP's local net is Class C and your own LAN
has Class C subnet

Then you simply have to make the CSLIP (why don't you use PPP?)
as a Point-to-Point Interface between and,
and after 2 sets up the CSLIP interface, it needs to add a default route
through it by
   route add default dev sl0

and on 1 you need to give the command
   route add -net netmask dev sl0

(sl0 is the interface name of the slip interface, if memory serves

If you used PPP, this should be put in /etc/ppp/ip-up (and you could
further increase your bandwidth by using software compression on both
