Cant' connect to User Portal from WAN

Should be straightforward, you have to use https.

The 8443 port is used for VPN so you should change that. Use something close to 4444, eg. 4443 or 4430 

BTW the admin panel shouldn't be accessible from everywhere, so I advice you to change that and use SSLVPN to connect to the interface.

Yo lo use como usted menciona pero en realidad no me deja acceder al portal de usuario. Dice que error al autenticar cuando pongo las credenciales de usuario

I use it as you mention but it does not really let me access the user portal. It says that error when authenticating when I put user credentials

Maybe you're trying with the admin account? 

Try to create a new user and password and retry. Write down your password and remember, it's case-sesitive!

yes I work thanks friend The problem is that passwords must be assigned in a sensitive way, that is, with security parameters and more complex
