I've been connecting to the edge-eu-free-1.hackthebox.eu vpn from my desktop just fine. I wanted to have a friend ssh into a tmux sesh on my vps so I could see if he had any ideas on one of the machines I've been trying to solve.
I scpd my connection pack to the vps, and ran it, it seemed to connect. For this machine (Bashed if it matters), there is a web shell that I have to use to create a reverse shell to my client. This worked fine on my desktop, but it refuses the connection when both of them are running.
Since the vps is headless, I can't use the webshell through the terminal, so I have to connect to it through my vpn on my desktop, while simultaneously connected to the vpn from my remote vps, listening to a certain port so the reverse shell works.
It seems like it doesn't like when I do both of these things. The reverse shell connection is rejected when I try listening on my vps. The connection will also just disappear for minutes at a time, and even though openvpn is still running, it no longer shows it as part of my network (this is for both clients, desktop and vps). However this only happens when both are running at the same time.
So ya, let me know if I can provide any additional info. Basically I want a way to connect to the hackthebox vpn network from two clients independently (I would be fine with different IPs, I just want to be able to actually run two).
