I did my first full stack (Firewall, Switch, WiFi) install today. No real problems, but some of the devices had to be repeatedly rebooted to get them to configure correctly.
Now that everything is in and it appears to be working well enough, customer has asked me for a VPN (they didn't ask about that before I did the install!!!)
I've got a machine inside of the network configured as a VPN server now, but I can't seem to poke any holes in the firewall.
I've got port 1701 UDP forwarded to my VPN machine, but I can't figure out where I'm getting stopped. I don't think it's a problem behind the firewall, because I've got 2 other ports forwarded to different machines, and those don't connect either.
I did an NMAP port scan on the network, and there are no open ports.
So what do I need to do to actually open the ports?
