I installed qubes-os 4.2
I need to do CTF’s on tryhackme and hackthebox.
I created appVM named ‘CTF’. I connect to my openvpn config from hackthebox in ‘CTF’ appVM. And reverse shell via netcat not work and ping or curl when I use python3 -m http.server on my ‘CTF’ appVM not work from remote machine.
I connected appVM to sys-net, but still not work.
So I have: sys-net -> CTF and use openvpn config in the CTF appVM.
Anybody play CTF’s on qubesos?
How I can allow incomming traffic from remote machine via openvpn to my appVM?
Since openvpn is used here to tunnel packets between the qube and the remote machine, everything port-related is only accessible within “CTF”. sys-net and sys-firewall can’t see anything because they only forward the encrypted traffic.
