Abstract: In some examples, a message is received from a wireless client device. The message includes an IP address of the wireless client device. It is determined whether an IP address offered by a DHCP server is the same as an IP address in a message received from the wireless client device. If the IP addresses are not the same, then a force renew DHCP message is sent to the wireless client device.

Abstract: The present disclosure discloses a network device and/or method for virtual private network client Internet Protocol (IP) address conflict detection in the wireless network. The network device receives, from a VPN client, a message that includes a first private IP address corresponding to a VPN client, and re-allocates a second private IP address corresponding to the same VPN client. The second private IP address resolves an IP address conflict between a tentative private IP address allocated for the VPN client by the VPN server within the wireless network and the first private IP address allocated for the VPN client by an ISP server external to the wireless network. The network device also transmits the first private IP address and the second private IP address in a single message, such as a single IP data packet, to the VPN client.
