Node License Count - NETGEAR FR314 Reference Manual

Reference Guide for the Model FR314, FR318 and FV318 Cable/DSL Firewall and VPN Routers
Stealth mode may cause problems with some applications, such as sending email. If your ISP's
mail server runs on UNIX or Linux (common for large ISPs), that mail server will attempt to send
you traffic whenever you try to send mail to it. That traffic is called authentication (or Identd) and
it uses TCP port 113. If your router is in Stealth mode, it will ignore the incoming authentication
packet, and the mail server may not forward your mail. If your router is not in Stealth-mode, it will
send a NACK-RST packet, which may allow the ISP's mail server to continue anyway.
If you have enabled stealth mode and you are having difficulties sending regular email or
NETGEAR logs or alerts out through a mail server run by your ISP, you may want to enable
forwarding of authentication (Identd) traffic in the Add Services menu. Follow these steps:
Go to the Add Service menu.
1.
Find Authentication in the "Add a known service" dropdown menu.
2.
Click the Add button.
3.
Go to the Services menu.
4.
Find the Public LAN Server box for Authentication near the bottom.
5.
Type in the router's LAN IP address.
6.
Click Update.
7.
This change will allow the router to respond to the ISP mail server's authentication request.

Node License Count

The Netgear Firewall/VPN Routers provide Internet access sharing capability for multiple users. A
"User" or "Node" is a networked device with an IP address, most commonly a computer. The
FR314 and FR318 firewall routers allow a maximum of 8, 20 or 45 users/nodes, while the FV318
allows 20 or 45 users/nodes. The router's 'node license' is initially the smallest of these numbers,
but can be increased in the amounts shown by purchasing node license upgrades from Netgear.
These node licenses are counted cumulatively, not simultaneously. When the firewall router is
powered on or rebooted, it starts counting LAN IP addresses against the license. When a computer
or other device connects to the LAN port of the firewall, the router detects it via broadcast, and
stores the computer's IP address in memory. Restarting the router will erase the stored IP
addresses and start the process all over again. When 8, 20, or 45 IP addresses have been stored in
the router's memory, the router will not permit any additional addresses to access the Internet.
Therefore, the router restricts the number of IP addresses on the LAN, not the number of
simultaneous connections to the Internet.
