MT2500A no access to internet, but wireguard works

Routers
1

Hey,
I have here a strange problem with MT2500A.
I can connect to it via wireguard as roadwarrior, but it jumps all the time between "ethernet green" and "interface is connected, but the internet can't be accessed". I can even surf the web via this wireguard gateway.

The configuration was never changed, there is no firewall which can block smth. DNS and gateway is the fritzbox. MT2500A has static IP within this range.

Whats the point of this issue?

Cheers

Hi,

Please test ping the 4 DNS addresses in your router management page to see if there is any packet loss.

There may be a problem with the network export.
If possible, try to reproduce the problem and then export the log.

By the way, is your device able to access the Internet at all times? Even if it says "internet can't be accessed".

If this is the case, you can turn off "Enable Interface Status Track" and the router will no longer detect it, but you will also not be able to use Multi-WAN features such as failover and load balance.

thanks!
the "ping" is greyed out, but all DNS servers on multi WAN are there and are enabled.

here is the system Log from today:

The strange thing is, I can access internet as roadwarrior via this MT2500A, but the MT2500A itself can not update plugins for example. It says then, there is no internet connection.

If I connect the roadwarrior to it, I can also ping all the DNS servers above (just via bash from my laptop/roadwarrior).
