point can act as a NAT server, which instantaneously rewrites IP
addresses and port numbers in IP headers so that packets all appear to
be coming from (or going to) the single IP address of the access point
instead of the actual source or destination.
When a device uses the access point as an IP router, the access point
replaces the IP header, which includes the device’s MAC address, IP
source address, and TCP/UDP port, with its own. You can configure the
DHCP server to indicate that the access point is the IP router when the
