I haven't seen anyone ask you what happens if you `traceroute -n` from
the OSR5 box. DNS issues can cause `traceroute` to appear to be failing
when in fact it is succeeding, but getting hung up looking for the name
of the machine whose reply packet it received.

I know you don't think you have DNS issues, but try it anyway.
