I installed a Proteon router running standard TCP/IP software to connect our
back bone net in our building with a private net in the same building (no
external gateway, simply a router connecting 2 disjoint subnets).

We have noticed some behaviour which seems to be a normal operation on the
gateway, but that it is very annoying.
It seems that the Proteon does some self testing of both of its Ethernet
interfaces and other internal hardware by sending small trash packets to itself
every so often through both interfaces.
The frequency of such tests is often enough that it is noticibly consuming
precious bandwidth already at a premium in our backbone which is carrying a lot
of XNS traffic.

Has anyone experienced such behaviour? Is there a way to reduce the frequency of
the tests?
