[AX4200] Wireguard problem

[quanguyen]

Hi,

I just got a new AX4200, got it updated to the latest firmware: 3.0.0.4.388_32464-g275a7df
Its WAN Connection Type is PPPoE.
WAN DNS settings (in LAN tab / DHCP Server, DNS fields are empty):

• Adguard Family -> 94.140.14.15, 94.140.15.16
• Forward local domain queries to upstream DNS: no
• Enable DNS Rebind protection: no
• Enable client auto DoH: Auto
• DNS Privacy Protocol: None

I have 2 questions about Wireguard and provided DNS:

1. Wireguard

I setup its DDNS (as my IP is dynamic): e5-...asuscomm.com
I enable Wireguard on my router with these configurations:

• Access Intranet: on
• Tunnel IPv4: 10.6.0.1/32
• Port: 51820
• Allow DNS: on
• Enable NAT: on
• Pre-shared key: on
• Private key ... , public key ...

I add new Wireguard client on router, then download Wireguard app on my iPhone and starts to connect. It does not work, cannot load a webpage.
In Wireguard app on my iphone, I change DNS to 8.8.8.8, it does not work either.

Did I configure something wrong? Please show me how to fix.

2. DNS
As specified in my WAN DNS settings, I am using Adguard Family provided in the router settings.

However, when I use with my WIRED computer -> Ads are blocked; else (with my wireless/wifi devices), Ads are not blocked.
Why? How should I fix this?

Best regards,

I'd like to add additional information on my question #2:
My WIRED computer uses static IP address, while my wireless devices use dynamic, i.e. IP addresses are obtained from DHCP server

I'm not familiar with that specific router. That sounds like 2 problems not one. I'll try to help with the Wireguard one, as that's the thread title.

• If as you say you are failing to connect to the router, then that's nothing to do with the router's DNS, because you are failing to get to that. => It's something at the client end which is failing.
  
  
• In Android the Wireguard app has a log file so you can see what it's doing, and in your case why it's failing.
  Find that, and post it here, redacting anything which looks like a key or a password.

I got my 2 questions/problems solved, by simply switching from AdGuard Family to AdGuard. All work beautifully
