I have a 3 bit subnet issued to me by my ISP, accessed via PPP over an
ISDN terminal adapter. I am currently just using my PC with Windows and
Netmanage Chameleon to generate the PPP link, providing my PC with standard
IP access to the 'net.
What I would like to accomplish is to have a dedicated box running something
like Linux that would serve as a router between my home ethernet and my ISP
connection. The software router should also be able to be configured to
demand dial the ISDN connection when it has packets to forward, and take down
the link after some period of inactivity. ISDN isn't quite free :)
Of course, a connection like this would be wide open to attack from the 'net.
For the time being, I would not be making available any services whatsoever to
the outside, so a firewall that discarded everything but that necessary for
internal machines to access the standard Telnet, FTP, NNTP, finger, etc. is
all that is necessary.
Of course, I could do all this (I don't know about the firewalling though) with
an Ascend or Combinet type box, but for now I need a cheaper solution. And
I expect hacking a Linux box to do the above would be rather educational.
Suggestions?
