• If a firewall is in place on the network an AP will use for backhaul, this must be
configured to allow traffic to and from the AP - see the port usage section below
Port Usage
All connections are outgoing. That is, they are initiated from the AP. Port usage has some
dependency on whether or not the AP is using IPsec.
With IPSec, the standard two ports are used:
Without IPSec, the following ports are used:
The following ports are also used. When IPsec is used, they may be inside or outside the
IPSec tunnel, depending on configuration:
2.2.2 nano3G AP Cooling
Special attention must be given to ensure a nano3G AP will meet its air cooling
requirements in its installed location.
Take the following points into consideration for the physical location of an AP:
• All AP models must be installed so that they are upright, to ensure proper air will
flow through the body of the AP to provide cooling.
• All AP models must not be installed in enclosed spaces where air flow is
restricted. This includes, but is not necessarily limited to:
• Roof or ceiling spaces
• Small cabinets
• Tightly enclosed shelf spaces
