Hey Erik,
Ah, I see, thanks for the additional details. I'm not super familiar with
HAProxy, but here are a couple of ideas:
1.) Add port forwards for each service, and configure HAProxy point to the
forwarded port. For example, you could add:
vm2.vm.network "forwarded_port", guest: 8080, host: 28080
Then, change HAProxy to point to localhost:28080 instead of 192.168.0.2:8080
2.) You might also consider creating firewall rules to isolate the guests
(i.e. running iptables or ufw with a shell provisioner).
Cheers,
Jeff
