4 The WWW screen opens.
Configure the following settings:
Server Port: The default web (HTTP) port that allows traffic to and from the WAN
is 80. If you open this port to allow for external communication requests, then
that would make quite a hole in the device’s security. So enter ‘81’ instead.
Server Access: Set this to WAN, to limit management requests to WAN only. This
prevents attempts from the LAN-side of the P-660H-T1v3s.
Secured Client IP Address: Choose Selected, then enter the WAN IP address
from which you intend to connect to the P-660H-T1v3s. This means only
connections from that IP address are allowed to open the port.
5 Click Apply.
4.4.3 Testing the DDNS Setting
Now you should be able to access the P-660H-T1v3s from the Internet. To test
this:
1 Open a web browser on the computer (using the IP address a.b.c.d) that is
connected to the Internet.
2 Type http://zyxelrouter.dyndns.org and press [Enter].
3 The P-660H-T1v3s’s login page should appear. You can then log into the P-660H-
T1v3s and manage it.
