DI-304/DI-304M ISDN Remote Router
Network Address Translation (NAT)
For small office environments, the DI-304/DI-304M allows multiple users on the
LAN to access the Internet concurrently through a single Internet account. This
provides Internet access to everyone in the office for the price of a single user.
NAT address mapping can also be used to link two IP domains via a LAN-to-LAN
connection.
LAN-to-LAN Enterprise Connections
The DI-304/DI-304M can dial to or answer calls from another remote access router
connected to a different LAN. The DI-304/DI-304M supports TCP/IP and has the
capability to bridge any Ethernet protocol.
Remote Dial-In Server
The DI-304/DI-304M allows Remote Dial-in Users to dial in and gain access to your
LAN. This feature enables users that have workstations with remote access
capabilities, e.g., Windows 98, to dial in using an ISDN terminal adapter (TA) to
access the network resources without physically being in the office.
