Hi everyone I was hoping to get some help if anyone has some time Ive run into a real conundrum!

I have 3 Intel NUCs each with one interface (eno1). Im trying to get three node setup (controller, network, compute) and I am having diffuculty with the external network since I am VLAN'ing to create the three networks needed. It "seems" like everything else is working - here is my configuration.

Controller node: VLAN 5 10.7.5.11

Compute: VLAN 5 10.7.5.31

VLAN 6 10.7.6.31

Network: VLAN 5 10.7.5.21

VLAN 6 10.7.6.21

VLAN 10 This is the unnumbered interface used for the external network

The network gateway is 10.7.0.1

So basically what is happening, I can create two instances on the tenant network (192.168.1.2 and .4) and they are able to ping each other and the tenant gateway (192.168.1.4). Ive assigned floating IP address' (10.7.5.102 and 103) and they are able to ping each other on the floating ip address but not out to any other host on the 10.7.5.x network nor out to the internet. I believe this is beacuse the br-ex is not working correctly (maybe because of the VLAN on the single interface?)

Here are some more configurations
