@high_voltage If you don't have access to the edge router, then you'd have to get your public IP by going to a website like https://whatismyipaddress.com or https://ipchicken.com. You can also do a google search for "what is my IP" and it will tell you.
Once you have the public IP, you would go to the "Client Export" utility, change the Host Name Resolution to "other", enter the public IP and then export your client packages.
Another option is to subscribe to a free DDNS service and enter a hostname instead of an IP.
