Changing IP Parameters
The IP Setup dialog box displays the IP addressing established during initial configuration for your
LAN and WAN ports. This dialog box enables you to change any of the original parameters as
necessary.
LAN
The IP Setup dialog box displays the unique LAN address and net mask you established during initial
configuration.
WAN Ports
If you are using your ProxyServer in an Internet application with one or both of the WAN ports
connected to the Internet and your ISP is dynamically assigning addresses to those WAN ports, then
you will want to leave the ISP Assigns Dynamic Address option active (checked).
If you wanted to change a WAN port to support a static IP address, you would select the WAN port
and disable (uncheck) the ISP Assigns Dynamic Address option. This activates the IP Address and
Net Mask fields for that port. You then need to enter a static IP address in the IP Address field and
assign an appropriate net mask in the Net Mask field. Then you would need to check the WAN Setup
dialog box and establish the Port Type for the selected WAN port; e.g., if WAN port 2 will be used for
remote access you would enable the RAS Enable option and if the port is being used as a dial in
feature, you would enable the Dial in Only option in the Port Type group.
If you change WAN port 2 to dial out to a telephone number other than your Internet Service Provider,
you would select WAN 2 and disable (uncheck) the ISP Assigns Dynamic Address option. This
activates the IP Address and Net Mask fields for WAN port 2. You then need to enter a WAN port IP
address in the IP Address field and assign an appropriate net mask in the Net Mask field. You would
then need to check the WAN Setup dialog box and change the Port Type for the selected WAN port
to enable the Dial Out option and enable the Asynchronous Gateway (AG Enable) option.
If you want to make WAN port 2 available for remote access, select WAN 2 and disable (uncheck)
the ISP Assigns Dynamic Address option. This activates the IP Address and Net Mask fields for
WAN port 2. Then enter a WAN port IP address in the IP Address field and assign an appropriate net
mask in the Net Mask field. Then check the WAN Setup dialog box and change the Port Type for the
selected WAN port to enable the Dial In option and enable the Remote Access Server (RAS Enable)
option.
