One other issue to look at besides IPXWAN;  make sure that you use 'ipx nlsp
rip off' and 'ipx nlsp sap off'  on the serial int's to turn off  RIP/SAP
updates.  I would also configure IPX on local int's on each router just to
make troubleshooting easier.  Add them to ipx router rip with no network as
you have for the serial int.
