mesh-announce does not listen on vlan-gt-20 #207

Closed AiyionPrime closed 3 years ago

For whatever reason, mesh-announce does not listen on dom0s vlan-gt interface.

By choice. We do not offer wireguard for the legacy domain. As far as I know it is not possible (except bruet force) to put a recent firmware into the legacy domain.

I'm not sure what you are talking about. I am talking about vlan-gt-20 an interface, that's created in roles/ffh.supernode/tasks/gt.yml. Do you talk about the (not existing) vx-0?

I need to read up, what vlan-gt was for again, but I think its part of connecting supernodes with each other, not wireguard.

My mistake. You are right.

Yep. The packages travel along the following path: bat0 -> vlan-gt-20 -> br-gt -> gt-sn01 -> eth0. This means that the batman packages are encapsulated in a vlan before being sent to the gretap interface. As gretap does not provide a multiplexing capability like "tcp port" or "udp port", this is our way to transport multiple domains over gretap.

No problem @1977er :)
