Re: opening a port

@S0RATA98

Here is a link for port forwarding guides for Zyxel routers: https://portforward.com/zyxel/

Check your router model and follow the relevant guide. If your router model is not shown, using this one is advised: https://portforward.com/zyxel/prestige-623/

Your ISP really should be able to assist with this if you run into difficulty.

Thanks.
