DDNS
The Router provides a list of dynamic DNS providers for you to choose
from. Dynamic Domain Name Server (DDNS) enables you to map a static
domain name to a dynamic IP address. This function allows you to create
a hostname that points to your dynamic IP or static IP address or URL.
Before you set up DDNS, you must obtain an account, password or key
and static domain name from your DDNS provider. The Router supports
five DDNS providers:
■
DynDNS.org
■
TZO.com
■
Dt DNS.com
■
No-IP.com
■
Zoneedit.com

Proxy ARP
Proxy ARP is the technique in which one host, usually a Router, answers
ARP requests intended for another machine. By “faking” its identity, the
Router accepts responsibility for routing packets to the “real” or intended
destination. This heightens the security for your network.
