How do I enable ZoneEdit dynamic DNS? …and how do I enable remote web GUI?

[sofakng]

I'm trying to enable a dynamic DNS service called ZoneEdit… (it's actually a DNS management service but it supports dynamic DNS and I believe pfSense also supports ZoneEdit).

The pfSense Dynamic DNS page says: "You must configure a DNS server in System: General setup or allow the DNS server list to be overridden by DHCP/PPP on WAN for dynamic DNS updates to work."

In the General Setup, I have the following option ENABLED:  "Allow DNS server list to be overridden by DHCP/PPP on WAN"

Why is the Dynamic DNS options still disabled?  I don't understand.

Also, how do I allow remote access to my pfSense Web GUI?

Thanks!

Dynamic DNS has nothing to do with the DNS options you are talking about.
Services –> Dynamic DNS

to access the webgui from the outside you need to create rule on the WAN interface that allows traffic from the WAN
