How to properly add linux bridge to pfsense in proxmox

[A Former User]

context: I'm a pfsense noob, sorry for the dumb questions

My current set up is I have pfsense (10.10.1.1) in a VM in proxmox (10.10.1.2) VE 7.3. Proxmox loops back to the pfsense VM. I created a linux bridge on the VE and added it to pfsense, named OPT1. I enabled OPT1, assigned it a static IPv4 (10.10.2.1/24), and then added a static lease for another VM to this interface (10.10.2.2)

The VM with 10.10.2.2 gets it's assigned IP but I have no access to the LAN or WAN. I'm guessing this is a rule thing? Admittedly I don't know what I'm missing. Thanks in advance

If you add additional interfaces to pfSense you need to create firewall rules on it to pass traffic. Otherwise devices on this interface cannot get to anywhere.

I had a feeling. These are the rules I've added to the new interface, what's wrong about them?

Seems as you could not do more from the point of rules.

Did you set pfSense as gateway on the VM?

Can you even ping the pfSense OPT1 IP?

@viragomann so I used route -n and it was indeed missing a gateway. I updated the VMs interface and added pfsense as the gateway. Now when I ping the gateway (10.10.1.1) I'm getting From 10.10.2.2 icmp_seq=1 Destination Host Unreachable whereas before it just said Network Failure

Edit: nvm I got it.

I gave the VM's network interface a static IP with /etc/network/interfaces and had to set its gateway as the IP of the linux bridge on the VE.
