It might be, that the [https://en.wikipedia.org/wiki/Maximum_transmission_unit MTU] of the network connecting the endpoints is smaller than the default (1500). By default the "option is set to" 1420, with an additional 80 due to wireguard overhead. Try adjusting it to something smaller: | |||
<syntaxHighlight lang="nix"> | |||
networking.wireguard.interfaces.wg0.mtu = 1000; | |||
#this is extremely small, bigger values can yield better performance. | |||
#networking.wg-quick.interfaces.wg0.mtu = 1000; #if you use wq-quick | |||
