wireguard-peer-update

This script allows to automatically update the public IP router address in a site-to-site Wireguard VPN when both routers have a dynamic public IP address and one of the two changes (tipically after a reboot).
It can be used by creating a netwatch on both routers...

Below the explenation:

xxxxxxxx.sn.mynetname.net is the hostname of the remote router (You can enable it on /ip/cloud/ddns...);
wgX is the name of the wireguard tunnel interface, generally it's called wg0, in this example it's also the interface comment;
wgXold and wgXnew it's the respective variable with the old and new ip address;
x.x.x.x is the remote wireguard IP address, for example 172.17.0.2;

  
/tool/netwatch
add down-script=":global wgXnew [:resolve xxxxxxxx.sn.mynetname.net]
    #:global wgXold [/interface wireguard peers get [find comment=\"wgX\"] endpoint-address ]
    :global wgXold [/interface wireguard peers get value-name=endpoint-address [find interface=\"wgX\"]]
    
    :if (\$wgXold != \$wgXnew) do={
    /interface wireguard peers set endpoint-address=\"\$wgXnew\" [find interface=\"wgX\"]
    /log info \"Wireguard wgX ip updated\";
    }" host=x.x.x.x interval=2m
