Disabling NAT
The router functions without performing any address translation on the packets passing through it.
Masquerading of packets originating from the LAN is disabled.
Address translation of packets arriving from the WAN is also disabled.
Any DNAT Configuration previously setup in the DNAT Configuration screen is disabled. This prevents the user
from adding any DNAT rules, which if allowed defeat the purpose of enabling Routing.
PPP General Group
PPP: Enable or disable PPP. The default is Disable. When enabled, the unit functions as a router. PPP must be
disabled to access the integrated cellular modem directly using telnet port 5000. If PPP is enabled, you cannot
access the integrated cellular modem.
Dial-on-Demand: Enable or disable Dial-on-Demand. The default is Disable. If you disable it, the router always
stays connected unless the Idle Time Out expires. When Dial-on-Demand is enabled, use the ‘Wakeup on Call’
settings under the PPP menu to configure the settings for re-establishment of the connection.
Idle Time Out: Set the amount of idle time that passes before the router timeouts. The default is 180 seconds. If
the time expires, the PPP connection to the Internet disconnects. Any IP packets from the LAN side or IP traffic
from the wireless side resets this timer and prevents the connection from dropping.
Connect Time Out: Set the number of seconds to wait for a connection while in receive mode before timing out.
Dialing Max Retries: Enter the number of dialing retries allowed. The default is zero, which means an infinite
number is allowed. Range 0 to 100.
Authentication Group
Authentication Type: Set the authentication protocol type that negotiates with the remote peer: pap/chap/pap-
chap. Default is pap-chap.
Username: Enter the Username with which the remote peer authenticates. You can leave this field blank, if
desired. Username is limited to 60 characters.
Password: Enter the Password with which the remote peer authenticates. You can leave this field blank, if
desired. Password is limited to 60 characters.
ICMP Keep Alive Check
Keep Alive Check: Enable or disable Keep Alive Check. The default is Disable. This is used to periodically check that
the Internet connection is up. If it is not, the router tries to reconnect.
Keep Alive Type: Select ICMP or TCP (the protocol type for Keep Alive).
Host Name: Enter the Host Name or IP Address for Keep Alive Check. No default.
TCP Port: Enter the TCP Port number to connect with the TCP server.
Interval: Set the number of seconds for Keep Alive Check. Default is 60 seconds.
