No Devices Connect to Pihole

Hi Guys

I have installed Pihole on my Synology using this exact guide from Wundertech: https://www.youtube.com/watch?v=OzI5DRfVAdc&t=558s
But when I was finished an checked the connected devices, wether my macbook nor my iphone was using pihole. One thing to say is, that the only difference to my setup is, that I used a bonded network interface in my synology. So I set my macvlan parent=bond0.
My Debug log is: https://tricorder.pi-hole.net/Viguf6Hl/

If anyone had a similar issue or takes their time to help me out, I would be really really thankful!

Cheers

Sascha
