Simultaneous Basic NAT and Napt | Paradyne 6351, 6341, 6301, 6342

3. Configuring the DSL Router

Simultaneous Basic NAT and NAPT

Simultaneous Basic NAT and NAPT (or PAT) is supported. In this mode, the servers (private IP addresses) using Basic NAT are configured and the devices (private IP addresses) using NAPT are optionally configured (static mappings). If not configured, the remaining private IP addresses default to NAPT.

Enabling Basic NAT does not disable NAPT. When both Basic NAT and NAPT are enabled, Proxy ARP can also be enabled, although it is only used for Basic NAT.

Applications Supported by NAT

The DSL routers support the following applications and protocols:

FTP

HTTP

Ping

RealPlayer

Telnet

TFTP
