Dratek 2830 Port 443 not Opening

Hi,

I cannot seem to get port 443 to open on my Draytek 2830. I have changed the SSL VPN and the HTTPS port on Management port setup to a different port number. I then opened the port and setup re-direction of the port to an internal IP.
I have tried using a online port scanner (a few different ones) and they all say the port 443 is not responding. Other ports respond but 443 won't.

Anyone got an ideas on this issue. It should be very straightforward but it driving me mad.

Thanks and kind regards,
Colin

Have you checked the internal firewall of the server you are redirecting the port to?

Hi Iruiz52,
Would that stop the online port scanner reporting the port 443 is not open?

Yes,

If you are forwarding https to an internal address and that port is not open or blocked on that server, port scanner will report port not open.

is it a windows server you are forwarding to? if so check the MS firewall or 3rd party AV with FW capabilities.

Hi Iruiz52,

It's a Windows 7 pc the 443 is being forwarded too. The 3rd party firewall is disabled and I have put rules in the windows firewall to not block port 443. still no joy.
Is there a way I can check the port 443 is open on the PC internally?

try the command below  

netstat -aon | find /i "listening"

also,

as a test try disabling the windows Firewall for a few minutes, while you test.

Hi, sorry for the delay in responding.
It turned out the website in IIS was not listening on this port.

Thanks for all you help.
