♦ Enable CLID Authentication – Limit the dial-in router to be called from
a specific ISDN number.
♦ Peer ISDN Number – If CLID Authentication is enabled, enter the
remote router's ISDN number in this field
♦ Link Type – Refer to Dial-Out Settings.
♦ PPP Authentication – Refer to Dial-Out Settings.
♦ VJ Compression – Refer to Dial-Out Settings.
♦ Callback Function (CBCP) – Checking here allows this router to accept
requests from a remote router for call back.
◊ Enable Callback Function - Checking here to enable this function.
The router owner will be charged the connection fee by the telecom.
◊ Use the Following Number to Callback:
- Callback Number: Check here and enter a callback number
for the router to call.
- Callback Budget: Specify a time budget for the callback

TCP/IP Network Settings
The following settings are required for proper LAN-to-LAN operation.
♦ My WAN IP – In most cases you may accept the default value in this
field. The router will then get a WAN IP address from the remote router
during the IPCP negotiation phase. If the WAN IP address is fixed by
remote, specify the fixed IP address here.
♦ Remote Gateway IP – Specify the IP address of the remote router.
♦ Remote Network IP – Specify the network identification of the remote
network. For example, 192.168.1.0 is a network identification of a class-C
subnet with netmask 255.255.255.0 (/24).
♦ Remote Network Mask – Specify the netmask of the remote network.
♦ RIP Direction – The option specify the direction of RIP (Routing
Information Protocol) packets through the ISDN WAN connection.
♦ RIP Version – Select the RIP protocol version. Specify Ver. 2 for
greatest compatibility.
♦ For NAT operation, treat remote sub-net as – Toggle between Private
IP and Public IP.
