DNS stops working when changing "Default allow LAN to any" rule to WAN gateway

[cephyr]

Hi,

if I change the Gateway of the "Default allow LAN to any rule" to my WAN Interface instead of default then the DNS stops working.

I want to change the gateway to my WAN interface to prevent the traffic going out of other interfaces such as openvpn.

Issue was stated here also:

Is there any solution?

Best regards
