Changing IP Parameters
The IP Setup dialog box displays the IP addressing for your LAN and WAN ports that were
established during your initial configuration. The IP Setup dialog box allows you to change any of the
original parameters.
The IP Setup dialog box displays the unique LAN address and net mask you established during your
initial configuration. If you are using your ProxyServer in an Internet application with one or more 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.
If you wanted to change a WAN port to support a static IP address, you would select the WAN port
and disable the ISP Assigns Dynamic Address option. This activates the IP Address and Net Mask
fields for that WAN 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 want to check the WAN Setup
dialog box and establish the Port Type for the selected WAN port, e.g., if the WAN port is being used
for remote access, you would want to enable the RAS Enable option; if the port is being used as a
dial in feature, you would want to enable the Dial in Only option in the Port Type group.
If you wanted to change a WAN port to dial out to a telephone number other than the Internet, you
would select the WAN port and disable the ISP Assigns Dynamic Address option. This activates
the IP Address and Net Mask fields for that WAN port. 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 wanted to change a WAN port to be available for remote access, you would select the WAN
port and disable the ISP Assigns Dynamic Address option. This activates the IP Address and Net
Mask fields for that WAN port. 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 In option
and enable the Remote Access Server (RAS Enable) option.
The DHCP (Dynamic Host Configuration Protocol) group allows IP addresses to be assigned by a
DHCP Server. In such cases, a PPP client connected to the WAN port will be on the same IP network
as the LAN port. Because the DHCP Server automatically assigns an IP Address for a PPP client
coming up on a "Client Only" WAN port, this feature can save IP addresses that otherwise would have
been taken up by the WAN port.
To enable DHCP, you must check the Client box and enter the IP address of the external DHCP
Server (e.g., Microsoft's DHCP feature) in the Server Address field. The Server Address is assigned
by your systems administrator.
