If, however, you firewall has multiple internal interfaces e.g. one for the intranet and another for DMZ servers etc. then you should place the Vyatta box outside the firewall. (linux/mac OS machines have this by default for OpenStack Docs: Native Open vSwitch firewall driver Historically, Open vSwitch (OVS) could not interact directly with iptables to implement security groups. Thus, the OVS agent and Compute service use a Linux bridge between each instance (VM) and the OVS integration bridge br-int to implement security groups. The Linux bridge device contains the iptables rules pertaining to the instance. In general, additional components between instances and Prepare the Linux Server - Palo Alto Networks The VM-Series firewall can connect using a Linux bridge, the Open vSwitch, PCI passthrough, or SR-IOV capable network card.

10 Linux brctl Command Examples for Ethernet Network Bridge
Packets that arrive on a bridge port and that are destinated to the bridge box itself will by default enter the iptables INPUT chain with the logical bridge port as input device. These packets will be queued twice by the network code, the first time they are queued after they are received by the network device.

You can even control ufw from a graphical interface. Ubuntu’s firewall is designed as an easy way to perform basic firewall tasks without learning iptables.
👍 🎉 I can access my running Linux service from any system on my network via my Windows host IP! Thanks for all the detail and Task Scheduler suggestion too. In addition, this workaround means localhost works too. I was trying to go down another route by forcing bridge mode of WSL virtual adapter, that didn't work.
