Subject: need to "fix" routing from agate, crystal and pearl
Tim / Tom --
Small routing problem going from agate/crystal/pearl to GSFC. Looks like
the application
host routes on these systems is going out over the ethernet interface.
Need to set up a static route
on each host for 169.154.0.0 to use the router that is directly peering
with NREN as a gateway. Any
questions or problems with this request, please feel free to contact me. I
will be out of the office this
week but I will read my email in the morning/evenings. Thanks for the help!
