Cannot reach FreeBSD from Qube but can reach Qube from FreeBSD

[*Null* **]

I have a FreeBSD HVM connected to a firewall VM. I also have a Fedora Qube connected to the same firewall VM. Networking between these was enabled using the iptables instructions from the Qubes documentation.

I can ping and access resources on the Fedora Qube from FreeBSD(I can transfer files to and download files from the Fedora VM).

However, I cannot do the same from the Fedora VM. It can ping the firewall, but not FreeBSD. Nor can it access resources on the FreeBSD system.

This confuses me because I would assume file transfer(from bsd to fedora) implies there is some bi-directional communication. But it seems to only work when initiated from one direction(from BSD).

All VMs can connect to the internet, FreeBSD can ping any vm, other VMs can ping other qubes based vms, but cannot ping FreeBSD.

What else must be done?

This works as advertised.
Can you check on your HVM that you are allowing incoming requests?
That's the obvious explanation for the scenario you have.

Ah, I had set ipv4 accept any, figuring that would be fine. But I wrote another for icmp and it worked to ping it.
Thanks
