Something is really confusing me here 
From the RPi I ping the following:
10.10.50.1 (GW - Works)
10.10.30.1 (VLAN GW, does not work from DNS, works from others on LAN)
1.1.1.1 (you know )
While sniffing the traffic I get this:
Blockquote

Nowhere can you see the ping to 10.10.30.1. It's like it's not heading to the DNS default GW.
I've checked iptables and there is nothing set up in there (that I can see).
This is a standalone PRi with only Pi-Hole on it. Nothing else.
Really confused now.
