Althea uses WireGuard over WireGuard for mesh routing. Each device maintains a link to peers using WireGuard and then also maintains it's connection to the exit over a multihop WireGuard connection.
Building working WireGuard tunnels over fe80 ipv6 link local addresses was a real pain. Packets sometimes arrive only to the interfaced scoped address and other times arrive without an interface scope. Requiring two tunnels to successfully listen on one port. -- Justin Kilpatrick [email protected] On Tue, May 12, 2020, at 2:56 AM, Dimitar Vassilev wrote: > Hi all, > > for my enlightenment can you please advise in which situation such > setups are useful? > > Thanks! > > > На чт, 7.05.2020 г. в 4:01 Derrick Lyndon Pallas <[email protected]> написа: > > > > Note for the list: IPv6 has a minimum of 1280, which means 1360 in the > > outer layer. ~Derrick > > > > > > On 5/6/20 4:54 PM, Jason A.
