There are 2 routers I have. Ones RT-AC86U is the older one because I bought RT-AX88U, I hope AC86U can use it for other applications not just retired.
AX88U is also a VPN Server, AX88U original using PPPOE to connect to ISP modem. Then AX88U gets wan IP to register to DDNS server. But I found AX88U float wan IP is not stable to connect, some time AX88U cannot PPPOE connect to ISP, so I lose the Wan IP during disconnect. Of course, during this time my VPN client is gone.
The following picture is my concept, is possible to implement it? and how to set up the AC86U and AX88U?
1. The ISP provides two PPPOE connections, ones is a static WAN IP(Green line), the other one can be a float WAN IP(Yellow line).
2. AX88U is passable to set dual wan connected to AC86U router and get wan IP from AC86U?
3. If AX88U cannot get wan IP from AC86U, that means AX88U only can keep alive connected to the internet, but cannot keep alive VPN server connected(because of no WAN IP for AX88U register to DDNS server), right?
4. If the above structure is not passable to implement, are there other suggestions to keep AX88U keep alive forever?
There is a survey from ASUS official website:

According to the sentence, I am not sure that AX88U really can get WAN IP from AC86U.
The sentence just mentions about "Now go to your LAN client, try to dial with your PPPoE account/password and you will get a public IP.". Does that mean LAN client is now equal my AX88U?
If AX88U becomes a LAN client, that would mean AX88U always got float WAN IP. Because AX88U dials PPPOE to get is a float WAN IP. But I hope when PPPOE float WAN IP crashed, the AC86U dials PPPOE to get static WAN IP and AX88U use the static wan IP from AC86U to register DDNS Server.
