Changing WAN Port Parameters
The ProxyServer is designed to provide the flexibility needed to meet today’s application needs. The
WAN Setup dialog provides the controls for WAN configuration. Each WAN port can be configured
independently of the others, or they can be combined depending on your application needs. Beyond
the basic controls offered in the Mode and Connection Method groups (described in detail in your
Help system) the WAN Setup menu includes many advanced features.
The sections that follow detail the function of those features and provide examples of how they can
be put to use. In addition, where relevant, they detail how certain features affect other dialogs in the
Proxy software.
Port Type
The Port Type group (on the WAN Setup dialog box) is used to configure the ports for specific
applications. The default settings for this group are Dial Out only and Proxy Enable.
This default setting works if you are setting up WAN port 2 to communicate with the Internet. If this is
the case, the WAN port must be enabled and the Port Type group configured for Dial Out Only or
Dial Out/In and the Proxy Enable option selected. As mentioned earlier, the Internet Setup dialog
box is used to configure the Internet Link Control Protocol, i.e., call connection and handshaking.
The Asynchronous Gateway (AG Enable) feature can be used on WAN port 2 configured as Dial
Out only or Dial Out/In. This feature is used to enable the ProxyServer to have a port available for a
remote user running a communications package to gain access to an available port on the
ProxyServer and dial out. When you enable this feature the Asynchronous Gateway group (at the
bottom of the dialog) becomes active. Refer to the Helps for a description of features in this group.
WAN port 2 can also be configured for remote access (RAS Enable) with either the Dial In Only or
Dial Out/In option enabled. If enabled, you must enable Remote Access and enter the WAN port IP
address in the IP Setup dialog box. This ensures that WAN port 2 and the Remote Address assigned
to it are in the same LAN segment. The remote IP address is assigned to the remote user.
