Hello @Fax,
Thank you for the clarification. It might seem like the previously added DNS entries may be corrupted. As mentioned previously, webfiltering will only work correctly if a single, either inherited from the ISP or specified manually, consistent DNS provider is used.
To move forward, could you try the following:
-
Manually set a single DNS on your mobile WAN interface (e.g., 1.1.1.1) in the Network → WAN page by editing the
mob1s1a1interface in Advanced tab:
-
On your PCs, leave DNS assignment to automatic;
-
To verify that the router is using only the desired DNS server, check this with the following command via SSH/CLI:
cat /tmp/resolv.conf.d/resolv.conf.auto
This should show the currently active DNS server(s) used on the active mobile WAN interface.
Let me know how it goes!
Best regards,
