I need some more details on this as I can't find anything online. Is this not just an encryption method of vtun?

As far as I know it is more like a fork.

Best reference I've found is some openWRT package [1] using some github repository [2].

[1] https://github.com/shangjiyu/openwrt-extra/blob/master/packages/vtun-sodium/Makefile
[2] https://github.com/shangjiyu/vtun

Second google search result is this issue.

I found the openWRT stuff, but I didn't bother looking in the Makefile. Thanks!

As far as I can tell, this fork just adds the new encryption mode chacha20poly1305, which doesn't exist in upstream vtun. Is selecting vtun as a tunnel type and adding chacha20poly1305 as encryption mode not enough? @dstelter

Florian made his own fork afaik, I'll bug him and ask. I think the protocol is incompatible beyond the cipher, so a new encryption type likely won't be enough.
