Requirements 
 
•  PCs in the local network have Internet access and can communicate freely with 
each other 
•  Desktop PC 2 should be able to configure the AP-600RP-USB (AP WAN IP must be 
accessible per PING), all other PCs in the Internet (e.g., Desktop PC 3) are blocked 
for the function. 
 
In order to be able to configure an AccessPoint over the Internet (WAN port), the firewall 
must be activated. Initially, the firewall is fully open – i.e., it does not block any data traffic 
to and from the public domain (Internet -> non-trusted). This means that rules must first be 
defined for correct operation (see overleaf for the configuration). 
 
GENERAL 
The firewall blocks all data from and to the non-trusted network: Initial set-
tings: Incoming: Discard and Outgoing: Discard. However, data over the 
router's interface (firewall) should remain active (Forward: Accept)
RULE 1 
PCs in the local network (192.168.1.X) with destination AP-600RP 
(192.168.1.254) are allowed to exchange data "through" the AP Æ Incoming 
data at the AP 
RULE 2 
Data originating from the AP-600RP (or Internet) (192.168.1.254) is forwarded 
to the appropriate PC in the local network (192.168.1.X) Æ Outgoing data at 
the AP
