Allocation Mode:
The passthrough mode; one of:
■
Off
: disables passthrough.
■
Passthrough
: assigns the Gateway's public IP address to a single LAN-side client.
■
Default Server
: forwards externally-initiated traffic to a specific LAN-side client. Use
this if you have a publically-available server, or have a network application that uses
arbitrary port numbers (for example, certain online games).
The available fields in this page change, depending on the selected allocation mode.
Select
Passthrough
from the
Allocation Mode
pull-down menu, to assign and reuse the
public WAN IP on a LAN computer. Use DHCP for addressing the designated passthrough PC.
The acquired or configured WAN address is passed to DHCP, which will dynamically configure
a single-servable-address subnet. This dynamic subnet configuration is based on the local
and remote WAN address and subnet mask.
IP Passthrough mode
The following fields are available in IP Passthrough mode.
■
Passthrough Mode:
The method used to assign the WAN IP address to the selected LAN
client:
■
DHCPS-dynamic
: the Gateway assigns its WAN IP address to the first LAN client that
requests a DHCP lease. It may be helpful, after the gateway has obtained a WAN
IP address, to cycle the desired LAN client's interface or reboot it. On disabling this
feature, you should reboot the LAN client.
■
DHCPS-fixed
: the Gateway assigns its WAN IP address to a specific LAN client. It
may be helpful, after the gateway has obtained a WAN IP address, to cycle the LAN
client's interface or reboot it. On disabling this feature, you should reboot the LAN
client.
■
Manual
: a LAN client must be manually configured with the gateway's assigned
WAN IP address and gateway information.
■
Passthrough Fixed MAC Address:
When Passthrough Mode is DHCPS-fixed, this is the
MAC of the selected LAN client.
