Note 1: If your ISP is providing a Dynamic IP address to your network, your WAN IP address may change even after applying the settings. Configure the ASUS DDNS setting to set up a fixed domain name.
Note 2: The Broadcast Support setting in 3-(2) allows broadcast packet transfers between VPN clients and local clients.
For example, the PC needs to send the broadcast packets to all LAN PCs to know which PC enables the Network Place Service.
The VPN client cannot send broadcast packets to the LAN while the Broadcast Support setting is disabled.
When Broadcast Support is disabled, VPN clients cannot detect the PC running Windows Network Place and will not be able to locate other PCs in the network. To connect to PCs in the LAN, VPN clients will manually have to type the IP address to connect to a PC in the LAN.
Note 3: In Step 3-(3), administrators can set up VPN MPPE encryption settings and VPN client encryption settings based on the table below:

FAQ
1. Can I connect to my home router from the external network using VPN if it has a private WAN IP address such as 192.168.x.x, 10.x.x.x, or 172.16.x.x?
When your router WAN IP is a private/virtual IP, it means that your router may be in the connection environment as shown in the figure below, and there is another router in front that assigns an IP address to your router. In this case, you must set up port forwarding on another router's virtual server page in order to use VPN to connect back to your own router from a remote external network. Please refer to the instructions on How to set up VPN server with port forwarding?
Note: To use VPN Server on your ASUS router, your router needs to have a public IP(WAN IP) from your ISP's internet service. This will allow devices on the internet to locate your ASUS router via a public IP(WAN IP).
If you are not sure of your public IP type, please check your Internet Service Provider (ISP).
2. Can the router use the private IP to set up the remote connection function?
Please note that if the router is using a private WAN IP address (such as connected behind another router/switch/modem with built-in router/Wi-Fi feature), could potentially place the router under a multi-layer NAT network. This feature will not function properly under such environment.
Private IPv4 network ranges:
Class A: 10.0.0.0 – 10.255.255.255
Class B: 172.16.0.0 – 172.31.255.255
Class C: 192.168.0.0 – 192.168.255.255
CGNAT IP network ranges:
The allocated address block is 100.64.0.0/10, i.e. IP addresses from 100.64.0.0 to 100.127.255.255.
