YazFi guest networks stop working when changing DNS or using VPN

[jsn2233]

My router is the GT-AX11000 and firmware is 3004.388.10_2_rog

Firstly, I will preface by saying like an idiot I tried to change the default IP to 192.168.1.1 unaware that this would cause issues with YazFi. I changed it back and the guest networks began to work again.

The issue I have now is that when I force DNS to my pihole at 192.168.50.8 or when I make a rule in VPN Director to redirect the guest network traffic through my wireguard VPN the network stops working - no internet.

As soon as I remove these rules and let the guest network go through the default DNS on YazFi (8.8.8.8) or disable wireguard VPN Director rule, it works just fine. Is there something I'm missing? The default subnet is using my pihole for DNS and is also redirecting traffic to my VPN. No idea why this is happening to my guest networks now. Only had this issue since I changed router to GT-AX11000, I was using the AC86U with an old firmware and my guest network used to funnel to my DNS perfectly before.

Edit: After I changed the default IP of my router back to 192.168.50.1 I removed YazFi and the config files, rebooted my router and then reinstalled YazFi just in case.

After trying what was listed here for the vpn, the vpn now works for my guest networks! Although you also have to make the script executable which wasn't mentioned in the post (as helpful as it was).

Now I just need to figure out how to make the DNS stuff work.
