Hi. I've noticed a rather annoying "bug" and not sure how to fix it. Has anyone else seen similar?

I am using latest FW and Modem FW.

The issue:

Network Setting > Home Network

I have two interface groups. "Default" and another called "Bridge1". When "Default" is selected I have the DNS set to "static" and the values are set to what I want, in this case, Quad9 (9.9.9.9 and 149.112.112.122). I then change the drop-down to "Bridge1" and I configure exactly the same settings. All good… aprt from no…

If at any time, the WAN connection drops or reconnects (even without doing a full reboot), when it reconnects the DNS values set for "Bridge1" LAN clients are forced back to those forced by the ISP. Even though "Default" interface remains set and even though I have set both of them to be "static".

For info here is what the WAN DNS entries are - these overwrite those shown in the above image.

Why does this happen to "Bridge1"? Surely setting "static" should mean exactly that. Not to allow it to change randomly. I do not have "From ISP" selected. It is so annoying when you notice this as you have to make the change at the router and then reconnect client devices to get them to pick up the correct DNS settings.

Any advice?

Thanks.
