Which port is being used to update DDNS?

Hi,

I need to port forward DDNS in order to allow me to update public IP. Does anyone know which port is used for this? If it's already taken, do you know how to change it on the router?

Thanks,

the port depends on the service, but ddclient updates are typically outbound, so no port forwarding should be needed...

It's the ASUS built in DDNS.
I have router inside a LAN, need to request LAN owner to port forward VPN and DDNS port

Are you sure? VPN _outbound_ you need to tell them the dynamic port? Or DDNS they need to open traffic from a dynamic port?

Edit to add: If you want to use DDNS so that you can VPN into your router, then for the VPN server, you need to open a port on the LAN firewall. But DDNS isn't a service you run, it's a service you connect to, so that is different.
