CSLIP / TCP/IP Guru Needed
I need some help with my network config. I'm hoping you can help me.
Here's my current configuration:
<---A--->1<---B--->2<---C--->
A is the IP subnet of my ISP
B is an IP subnet for a CSLIP link between 1 and 2
C is the IP subnet of my LAN
1 is my internet "gateway" - running Debian
2 is my internet "router" - running Debian
The only reason the B subnet exists is as a "bandwidth limiter". My ISP
only wants me to use 112Kbps, so to create an artificial bottleneck, I put
a system (#1) on his LAN and set up a direct CSLIP link between that box
and our LAN.
This system is working great. All routing is configured and most
everyone's happy.... Except me.... <grin>
The way things are configured, I've had to assign a whole subnet to B to
configure routing. I've used a .224 mask on a Class C to create 6 subnets
of 30 hosts. I need every address I can get and right now, I've got 28
wasted addresses on the B subnet - only two addresses are needed as it is a
direct CSLIP link - basically the "sl0" interface on 1 and 2.
My questions are:
I once read/heard somewhere that it might be possible to do unnumbered
CSLIP interfaces. Is this possible? If so, how do I do it? (Pointers to
manual/docs gladly accepted....)
Do you have any suggestions for other alternatives on how to limit the
bandwidth above? Cost _is_ an issue.
TIA for your comments,
