IP Port Configuration
This dialog allows for the configuration of IP parameters that are generally applicable to IP
proxying on all ports.
8. The Secured LAN Port Parameters have to be changed to your private (secure) LAN
parameters. Enter your Secured LAN Port IP Address in the IP Address field, followed by
the Net Mask in its field, and finally the Default Route IP address.
The Secured LAN Port IP Address can be an unregistered IP address. The Internet LAN
port IP address and the Gateway IP address must be in the same IP network.
9. The Internet LAN Port Parameters depend on how LAN 2 on the ProxyServer is
configured. If a DHCP Server is providing IP addresses, click on the OK button and
proceed to step 13.
If a DHCP Server is not providing the IP address, then click on the DHCP Client option
and the IP Address and Net Mask fields become active. Enter your valid Public LAN IP
address in the IP Address field, also, enter your valid Net Mask in its field.
DHCP Relay Agent does not apply.
10. If a cable modem, DSL modem, or your public (Internet) LAN is connected to LAN 2 on
the ProxyServer, the WAN Port Parameters are not required.
The WAN Port Parameters are only required if a device is connected to the RS-232/
V.35 connector on the back of the ProxyServer. If your ISP for your local (secured LAN)
dynamically assigns the WAN port IP addresses, you do not have to do anything for the
WAN Port Parameters. Proceed to the step 12.
If a static WAN Port IP address needs to be assigned, click on the ISP assigns Dynamic
Address check box to disable the feature, then click on the IP Address field and enter
your registered WAN Port IP address. Also, enter the Net Mask for WAN port.
11. If a DHCP Server is not providing the IP addresses in step 9 and a cable modem, DSL
modem, or your public (Internet) LAN is connected to LAN 2 on your ProxyServer, then
click on the Internet LAN IP Address field and enter the valid Gateway IP address (i.e.,
the IP address of the cable or DSL modem, or your public (Internet) LAN router’s
address).
If a static WAN Port IP was assigned in step 10 and the Internet access is through the
RS232 connection on the back of the ProxyServer, then click on the Internet Gateway
Parameters WAN option.
12. Click OK.
