Can't disable User Portal from WAN

SSLVPN requires the User Portal and will open the User Portal, if enabled. 

Yes, but I disabled the User Portal in WAN Zone and it still stays open. I just want to have it opened in LAN. Or do you want to tell me there is no way of disabling it when we want to use SSLVPN?

Device access works on a port base. SSLVPN and User Portal can share the same port (for example 443). If you disable User portal but use 443 for both, the SSLVPN device access rule will still allow the port 443 on WAN.
