Yes, it supports.
If the AP is on the NAT intranet,
You do not need to configure the static IP address mapping or port mapping for the AP. You just need to configure the source IP address conversion to ensure the connectivity between the AP and the AC.
If the AC is on the NAT intranet,
1. On the egress router, configure mapping for UDP ports 5246 (control channel) and 5247 (data channel) with an AC address indicated by option 138.
2. The IP address of the AC (optional 138 IP address) on the AP is the public network address of the AC after mapping.
If the AP and the AC are on its own NAT intranet, the above three configurations must be met.
