Yep, that was it. Thanks very much. The fact that it mostly worked even
with the wrong port configured was somewhat confusing. If your neighbour
changed their port config, you could possibly be having these problems for
some time before realising. It would be nice if these could be reported
as conection failures to the neighbour rather than as an inability to
contact the source site.
