Configuring your Linux machine to act as a router is very
straightforward. The steps you must take are:
1. Build your kernel with IPX, Ethernet and /proc support.
2. Obtain, compile and install the ipxd daemon program.
3. Boot the new kernel and ensure that each of the Ethernet cards has
been properly detected and there are no hardware conflicts.
4. Enable the IPX protocol on each of the interfaces using the
ipx_interface command described above.
5. Start the ipxd daemon program.
I actually still have my CNA for 6.5, but haven't had to run IPX in years.
Start the routing daemons
The kernel software itself actually does the IPX packet
forwarding as it does for IP, but the kernel requires additional
programs to manage the routing table updates. In the case of IPX
two daemons are needed and both are supplied with lwared:
ipxripd manages the IPX routing information and ipxsapd manages
the SAP information. To start the daemons you need only specify
the location of where they should write their log messages:
# ipxripd /var/adm/ipxrip
# ipxsapd /var/adm/ipxsap
