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.)
