WAN IP Address
Used to enter the IP address for the IR-IP WAN interface, i.e., the IP address to be
used by IP hosts on the WAN to reach this IR-IP interface module.
If the WAN IP Address field remain blank, IR-IP operates in the Unnumbered
Router Mode.
WAN IP Mask
Used to enter the IP subnet mask for the WAN interface.
Default Gateway
Operation without Default Gateway
The IP interface module is intended to enable the extension of LANs through the
SHDSL link. Therefore, its default routing operation is different from the default
routing operation of standard IP routers:
IR-IP forwards packets with destinations not located on the local LAN through
the WAN interface
Packets received from the WAN interface and destined to hosts located on
the local LAN are forwarded to the LAN; other packets are discarded.
The default operation is used when the Default Gateway field is blank.
Operation with Default Gateway
You can instruct IR-IP to send packets with destinations not located on the local
LAN to a specific router, which is called the default gateway. The default gateway
must be connected to the local LAN.
To use this option, enter the IP address of another router attached to the local
LAN in the Default Gateway field.
