Hi i am trying to build a PFsense machine that can also run lxc containers under it...
my bridge looks like this

and PFsense is working great for things i connect to my switch...
the issue is when i try to to connect a LCX continer to the net

2. resolv conf
# --- BEGIN PVE ---
search local
nameserver 192.168.1.1

What you're trying can't work.

You use 192.168.2.1 on your vmbr1, but it's also supposed to be a Gateway.
That IP belongs on the pfsense interface, not Proxmox.
Proxmox is not a router and does not know what to do with the traffic.

You usually only need one IP on your Proxmox (for management), unless you're using a cluster, corosync, etc.
 
Remove the IP from interface vmbr1.
Add vmbr0 (wan) and vmrb1(lan) to your pfsense.
Add vmbr1 to your LXCs.

Configure your pfsense accordingly.
