2.2.3 Port Usage
This information is provided in case it is needed for configuring local on-premises
equipment, especially any hardware firewalls between the AP and the rest of the backhaul
network.
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:
These ports are used and allowed through the firewall where IPsec is used:
The following ports are allowed through the firewall independently of IPsec configuration.
For example:
AP > Firewall > DHCP Server
