NetNAT NN1-3E-Enterprise

The NN1-3E-Enterprise is a very powerful IP Router, Internet Firewall and enhanced RFC 1631 NAT device for the Internet user or provider. It is used where there is an existing Internet connection with Ethernet, or in a new Internet connection where a separate Wide Area Router is desired.

NN1-3E Specifications

The NN1-3E model contains:

Full NetNAT Firewall features
Three combination Ethernet interfaces, with coax, AUI and TP connections
Dynamic Mapping for 256 simultaneous client sessions
Fixed and Port Mapping for 64 virtual hosts

Hardware watchdog timer
Online manual via builtin WWW server
Substantial Cost Savings!
One year free software upgrades

Shown here, the three-ethernet NN1-3E provides secure connection between a vulnerable "public" LAN segment and two internal "private" segments. The IP Addresses of all devices on the private segments are hidden from the outside. Client applications on the private segments work without modification.

Servers on the private segments may be shown or hidden from the outside as the user wishes. The two private networks may see each other through the NetNAT's IP Router function, or hidden from each other if desired.

Substantial Cost Savings!

If you have two internal networks to protect with a Firewall, you need a more capable Firewall and a three-ethernet IP router. If you use our smallest NetNAT, you still need to spend $5000 or so on a big router. Our NN1-3E does all of the jobs at the same time.
