[Commotion-dev] meshing over ethernet

[Chris Ritzo]

Miles,
I was discussing this thread with some other team members this morning,
and we think you've confirmed a bug that we found in our 1.1rc2
connectivity tests.

Those tests confirm that two nodes meshed via ethernet will work when
not signed and fail when signed. Your report that turning off Serval
signing makes the center Buffalo node work properly.

Our team is still debugging this and will be pushing feedback to Serval
about it, however in the interim, turning off route signing via Serval
should solve this for you.

I'm sure Josh and Will can weigh in on more specifics related to the bug.
