Can one do multicast over wireguard?


Frustratingly enough, apparently not as I could never get it to work. It is pretty easy to set up a vxlan tunnel over wireguard if you absolutely need stuff like that though.


Oh hadn't thought about that, thanks. 'need' is a big word here but sometimes you can't change the client and server apps so, having support for the basic (although niche) features in the lower layers helps migrating smoothly.
