Normally, you can log in Vilfo over its DNS name admin.vilfo.com, or its local IP 192.168.0.1 that is the default IP address.
There is possibility to access Vilfo user interface over a custom domain name.
For that, you should first enable WAN access, and click Update.
Then enter the domain in the field Alias#1 , and click Update again.
If you would like to use a fully qualified domain name, make sure to have that domain pointed with an A record to your public IP address provided by ISP.
