How to configure interfaces/bridges between 2 PA VMs in proxmox

Howdy folks,
I have deployed 2 PA VMs within proxmox. I want to play with routing between these 2 PA VMs. Currently, the PA VMs can't ping each other using dataplane interfaces but they can using management interfaces. This is not a routing issue but rather an issue of how to configure interfaces or linux bridge or OVS bridge. Again, I have no problem pinging or reaching the management's GUI of these firewalls.
Proxmox is hosted by an old gaming laptop which only has 1 nic. I tried adding USB to ethernet to add a 2nd nic but then that caused issues with /etc/network/interfaces that I had to remove. (I don't think I need to add a second nic to play with routing between these 2 VMS?). I shouldn't need to do any vlan tagging or configure vlans?
So,
Proxmox
[OVS bridge(binded by physical nic enp59s0) - vmbr2- 192.168.7.20/24]
Because of this OVS bridge, PAVM1 mgt interface [net0](192.168.7.16) and PAVM2 mgt interface[net0] (192.168.7.17) can ping each other)

[OVS bridge - vmbr99(binded by no physical nic and no ip addressing)]

PAVM 1 dataplane interfaces
[Vmbr99][net1]- eth1/1 99.99.99.1/30

PAVM 2 dataplane interfaces
[VMbr 99][net1]- eth1/1 99.99.99.2/30

Hi!
do you have any firewall rules enabled? You can try disabling the firewall on the datacenter and node level to rule it out.
Also can you reach the dataplane interface ips from the host?
 
Hello ggoller
firewall is set to no on datacenter and the node.
The host (proxmox) can't reach the datacenter IPs, and that's ok. What should occur is that these virtual firewall interfaces should be able to ping each other and I'm assuming they can't because of how I setup OSV bridge?
