 To make the change take affect after a reboot, on Ubuntu 18.04 and later edit the relevant file in the `/etc/netplan` directory (see `man netplan`).

+#### Note for WireGuard iOS users
+
+As of WireGuard for iOS 0.0.20190107 the default MTU is 1280, a conservative value intended to allow mobile devices to continue to work as they switch between different networks which might have smaller than normal MTUs. In order to use this default MTU review the configuration in the WireGuard app and remove any value for MTU that might have been added automatically by Algo.
