Well, this is a new challenge. I muttered, sipping my coffee in front of the monitor. The VPS my friend gave me wasn't as easy as I thought. I intended to experiment with a mail server and other internet services on it, but I was greeted by a confusing firewall.
Access from outside? Impossible. The only way in was through a palo alto globalprotect VPN (via openconnect command)
The first clue was the web server, free from the firewall and accepting connections from the internet. Hmm, interesting.
However, one thing tickled my mind. The output from this command on VPS:
```
$ lspci | grep -i vga
00:0f.0 VGA compatible controller: VMware SVGA II Adapter
```
indicated that this server was running on VMware. So what do the actual network topology and configuration looks like?
I’m not looking for suggestions that involve third-party services like proxies or portmap.io. What I really need is guidance on how to audit the network and identify vulnerabilities so I can configure the firewall correctly.
Sure, I can provide more details as needed to help out. Just let me know what you need, and I’ll be happy to fill in the gaps.
