configuration of a linux router
Folk,
My LAN has a Debian router, joule, and two subordinate
machines, curie and heaviside. The three connect to an
old Linksys 10Base-T hub. joule connects to a
cable modem through a second NIC and runs
ipmasq.
Currently I want to add a third NIC to joule,
remove the hub and connect each of curie and heaviside
to a NIC in joule using a crossover cable.
All appears OK except that curie and heaviside fail to
communicate with each other.
The output of cat /etc/network/interfaces
and netstat -r follow.
Thanks for any ideas, ... Peter E.
