I have one system w OSCAR 1.3 where pfilter was set to off at all run levels.
Another system running OSCAR 2.2 had alot of installation and start-up problems
because of incorrect NIC drivers, APIC, IRQ and other setup issues. In the
process of troubleshooting involving many hands and heads, the default pfilter
settings may have gotten changed. I don't really know at this point.
Thanks for your feedback. I have set pfilter off on run levels 3 and 5 for the
internal nodes.

No. OSCAR's pfilter default configuration should allow any ports to be
opened between any of the OSCAR nodes.
Was it not configured this way?
