Ipx won't forward packets across two networks with different sized link
layer headers. I am running two networks one Arcnet and one 100VG anylan
network. Ipx will not forward as there is a bug in the code for it.
Please visit fa.linux.net and read Alexander S. Agranovsky
(firstname.lastname@example.org)'s note which contains a patch to fix the bug.
This is a kernel bug that should be fixed by in version 2.2.16 or later.
