Wifi bridge - cannot access bridged devices from main network

I have a MR8300 acting a wireless bridge, which works great allowing my hard wired devices access to my main wireless network. My issue is that when connected to the main wifi network, I cannot access these devices (my proxmox server most notably). What am I doing wrong?
Here is my interfaces tab if it helps:

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:

At first sight, everything looks good... Can you ping / traceroute the proxmox server from the main network?

I cannot, only when I'm wired in via the bridge

Could this be a firewall related issue? Do I need to look at "Bridge Firewall"?

Fixed it, firewall was inproperly configured. Made sure it matched this https://openwrt.org/docs/guide-user/network/wifi/relay_configuration#check_firewall_zone_settings and all works now!
