We use batman-adv as mesh protocol. While wireguard is layer 3 we need to have layer2 over this tunnel. so i tested wireguard + gretap + batman-adv successfully. compared to a other known layer2 crypted tunnel protocol (fastd) this is 3 times faster, which is mainly due to wireguard is a kernel-module and fastd lay in userspace. (-> context switche) i testet on weak devices, because this is what is deployed in big numbers in our (and many other) Freifunk community. also there are plenty of packets and stuff - so this explain the relative low throughput. At least compared with clean linked test-setups.= hope this explain my motivation and the reason why i test this in this special scenario.
