HTTPS
HTTPS (HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a web
protocol that encrypts and decrypts web sessions. Secure Socket Layer (SSL) is an application-level
protocol that enables secure transactions of data by ensuring confidentiality (an unauthorized party
cannot read the transferred data), authentication (one party can identify the other party) and data
integrity (you know if data has been changed).
HTTPS on the ZyWALL relies upon certificates, public keys, and private keys to securely access
the ZyWALL using the web configurator. The SSL protocol specifies that the SSL server (the
ZyWALL) must always authenticate itself to the SSL client (the computer which requests the
HTTPS connection with the ZyWALL), whereas the SSL client only should authenticate itself when
the SSL server requires it to do so (select
Authenticate Client Certificates
in the
Remote Mngt,
WWW
screen).
Authenticate Client Certificates
is optional and if selected means the SSL-client
must send the ZyWALL a certificate. You must apply for a certificate for the browser from a CA
that is a trusted CA on the ZyWALL.

SSH
SSH (Secure Shell) is a secure communication protocol that combines authentication and data
encryption to provide secure encrypted communication between two hosts over an unsecured
network.
5.17 UPnP Overview
Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for
simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a
network, obtain an IP address, convey its capabilities and learn about other devices on the network.
In turn, a device can leave a network smoothly and automatically when it is no longer in use.
All UPnP-enabled devices may communicate freely with each other without additional
configuration. Disable UPnP if this is not your intention.
Windows ME and Windows XP support UPnP. See the Microsoft website for information about
other Microsoft operating systems.
