1. When Local ID Content is blank which means user doesn’t type anything here, during
IKE negotiation, my ID content will be “My IP Addr” (if it’s not 0.0.0.0) or local’s
WAN IP.
2. When “Peer ID Content” is not blank, ID of incoming packet has to match our setting.
Or the connection request will be rejected.
3. When “Secure Gateway IP Addr” is 0.0.0.0 and “Peer ID Content” is blank, system
can only check ID type. This is a kind of “dynamic rule” which means it accepts
incoming request from any IP, and these requests’ ID type is IP. So if user put a such
kind of rule in top of rule list, it may be matched first. To avoid this problem, we will
enhance it in the future.
Appendix 6 Embedded HTTPS proxy server
HTTPS (Hypertext Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a
Web protocol developed by Netscape and built into its browser that encrypts and decrypts
user page requests as well as the pages that are returned by the Web server. HTTPS is
really just the use of Netscape's Secure Socket Layer (SSL) as a sublayer under its regular
HTTP application layering.
The ZyWALL’s embedded HTTPS proxy server is basically an SSL server which
performs SSL transactions, on behalf of the embedded HTTP server, with an SSL client
such as MSIE or Netscape. As depicted by the figure below, when receiving a secure
HTTPS request from an SSL-aware Web browser, the HTTPS proxy server converts it
into a non-secure HTTP request and sends it to the HTTP server. On the other hand, when
receiving a non-secure HTTP response from the HTTP server, the HTTPS proxy server
converts it into a secure HTTPS response and sends it to the SSL-aware Web browser.
By default, the HTTPS proxy server listens on port 443 instead of the HTTP default port
80. If the ZyWALL’s HTTPS proxy server port is changed to a different number, say
8443, then the URL for accessing the ZyWALL’s Web user interface should be changed
to https://hostname:8443/ accordingly.
Appendix 7 Multiple WAN Access
Because of the expansion of broad band service, the bandwidth is more and more cheap.
Some of audio and video applications become usable, such as VoIP and video conference.
The company will subscribe several links for different application. They may use it for
VoIP, Backup line, Load sharing, and extend bandwidth. Thus they will need a device to
manage these kinds of application.
The ZyWALL has two independent WAN ports, so it offers the ability to configure a
secondary WAN port for highly reliable network connectivity and robust performance.
The user can connect WAN 1 to one ISP(or network), and connect the other to a second
