Hi.

Doing a port scan on my firewall this output is shown:

Open port: 1723/tcp
Firmware Version : 257
Vendor Name : FreeBSD mpd-3.18

Is it possible to spoof this in any way? Like to show nothing on the 
port 1723? I need PPTP to be open to be able to use VPN, but I would 
hope it was possible to block any info coming out.

Btw; I'm running v1.22 NET48xx version.
