Full MTU fragmentation?

I just dug through the docs and I can’t really see any information on how fragmentation works with Zerotier.

I’m wanting to pass full frame MTU across zerotier, but the WAN links are all limited to 1500MTU ie fragmentation.

I have a number of locations with mixed internet choices. ie, some have a high speed cable connection and another has 4 DSLs that I want to bond. The core has a 10G link.

I’m hoping zerotier can handle all this and fragmentation as well. Ie, a zerotier box connected to all 4 DSL to use zerotier multipathing.

Note, this is a ‘transport’ mode where the client devices wont run zerotier but be routed over a zerotier connection.
