You can use the command line interface to specify whether TCP/IP is enabled,
identify a default Gateway, and to enter TCP/IP settings for the Cayman Gateway
LAN and WAN ports. If PPPoE is turned off, you must specify settings for Ethernet
A and B separately. If PPPoE is turned on, you can omit the A|B labels.
BOTH
Enables or disables TCP/IP services in the Cayman Gateway. You must enable
TCP/IP services before you can enter other TCP/IP settings for the Cayman Gate-
way. If you turn off TCP/IP services and save the new configuration, the Cayman
Gateway clears its TCP/IP settings.
BOTH
IPSec PassThrough supports VPN clients running on LAN-connected computers.
Turn this setting off if your LAN-side VPN client includes its own NAT interopera-
bility solution.
DSL
Specifies whether virtual circuit n on 3220-H is active (where n is a number in the
range 1-8). You must enable a virtual circuit before you can enter other settings
for it.
DSL
Assigns an IP address to the virtual circuit. Enter 0.0.0.0 if you want the virtual cir-
cuit to obtain its IP address from a remote DHCP server.
DSL
Specifies the broadcast address for the TCP/IP network connected to the virtual
circuit. IP hosts use the broadcast address to send messages to every host on your
network simultaneously.
The broadcast address for most networks is the network number followed by 255.
For example, the broadcast address for the 192.168.1.0 network would be
192.168.1.255.
DSL
Specifies the subnet mask for the TCP/IP network connected to the virtual circuit.
The subnet mask specifies which bits of the 32-bit binary IP address represents
network information. The default subnet mask for most networks is
255.255.255.0 (Class C subnet mask).
