HTTP or HTTPS?

Question

I'm a little confused on selecting HTTP or HTTPS..............................I understand one is secured but how should my set up be?
Web Access
Access Server
HTTP (HyperText Transport Protocol) is
the communications protocol used to connect to servers
on the World Wide Web. HTTPS uses SSL (Secured Socket
Layer) to encrypt data transmitted for higher security.
Select
HTTP or HTTPS. The default selection is HTTP.
Wireless Access Web
If you are using the Router in
a public domain where you are giving wireless access
to your guests, you can disable wireless access to the
Router’s web-based utility. You will only be able to access
the web-based utility via a wired connection if you disable
the setting. Keep the default,
Enable, to enable wireless
access to the Router’s web-based utility, or select
Disable
to disable wireless access to the utility.
Remote Router Access
Remote Management
To access the Router remotely,
from outside the network, select
Enable.
Management Port
Enter the port number that will be
open to outside access. You will need to enter the Router’s
password when accessing the Router this way, as usual.
Use https
To require the use of HTTPS for remote access,
select this feature.

Answer 1

My take on this is to use https where ever you can, keeping in mind that it has to be supported on both ends, both the client and server ends.  But especially for remote administration of the router, that should definitely only be done via https.
