2.3.3 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.
Port Usage Before IPsec
The AP can use any of the following ports before the IPsec tunnel is established:
The AP may continue to use some of these ports outside the IPsec tunnel. For example, for
contacting NTP servers.
Port Usage With IPsec
With IPsec, the standard two ports are used:
The AP will need to continue using these ports:
Protocol Destination Port Use
udp 67 DHCP
udp 68 DHCP

tcp 443 HTTPS for connecting to the Redirector
tcp 80 HTTP for first CRL download for a new AP or after
