I have a strange issue. All of my proxmox guest's (VM & LXC) outgoing traffic seems to be blocked. The hosts have no issues, only the guests. If I disable the Datacenter level firewall, the outbund traffic works. When I re-enable the firewall the outbound traffic stops working. I do not have any explicit outbound rules set up on the individual guests.

This also seemed to randomly start. It was working with no issues and then it randomly stopped. Its possible I changed something but nothing I can think of to cause this.

I have the default policies in place below:
