Multiple Protocol over ATM Mode
Parameter Description
DNS Enter a domain name server IP address.
WAN IP Enter an IP Address for the Barricade WAN interface.
Subnet Mask Enter a subnet mask.
VPI/VCI Virtual Path Identifier (VPI) and Virtual Circuit Identifier
(VCI.)
Data flows are broken up into fixed length cells, each of which
contains a Virtual Path Identifier (VPI) that identifies the path
between two nodes, and a Virtual Circuit Identifier (VCI) that
identifies the data channel within that virtual path. Each virtual
circuit maintains a constant flow of cells between the two end
points. When there is no data to transmit, empty cells are sent.
And when data needs to be transmitted, it is immediately
inserted into the cell flows.
Default Gateway Enter a default gateway IP address. If the Barricade cannot find
the destination address within its local network, it will forward
the packets to the Default Gateway (usually your ISP will
supply this address.)
