I’m having the same issue with the devel machine. The vpn works fine, I can ping the gateway, but no nmap command works on the target, traceroute stops at the gateway. I’ve also tried the pwnbox, changed files+servers, reset the target machine and it’s not working. I got vip which means I should have access to it, I don’t know what to do at this point. THM works seamlessly compared to this.

I’m sure you need to disable all other VPN services you might have running. You can only use 1 VPN that is the VPN file provided by Hack the Box.

Not sure if that’s what you are experiencing?

Where is this IP from? Try typing “ ip -a “ to see the tun01 IP address.
