An AP sets up a data tunnel to a remote network and monitors a remote DHCP session between a client device and a remote DHCP server in the remote network. The remote DHCP server assigns a remote IP address to the client device, and communication between the client device and the remote network is based on the remote IP address. In response to determining completion of the remote DHCP session, the AP initializes a local DHCP session with a local DHCP server in a local network to obtain a local IP address for the client device. Communication between the client device and the local network is based on the local IP address. In response to detecting the client device roaming from the AP to a target AP, the AP forwards the remote and local IP addresses and session data of active sessions on the client device to the target AP.
