How to make the 1C Enterprise 8.3 server available on port 1560 only from the local network or from the same physical server?

Question

1C-Enterprise

We have a physical server, they stand and work on it:
- Server 1C: Enterprise 8.3
- MS SQL Server 2014 (1 base)
- RDP for 10 users
This is all done on the basis of Windows 7 (not a server OS) .... just not laugh and do not twist at the temple, it's easier for a number of reasons. )))
Since the web server and mail still hang on the same server, we cannot completely make it intranet. In MS SQL, of course, there is no access from the outside, this is limited by the server settings, RDP has also been moved to a non-standard port, since bad hackers are tired of breaking.
The question is: how to close port 1560 (as far as I understand, the 1C server hangs on it) for access from the outside (from the Internet) and make the connection to 1C available only from localhost or from another computer on the local network?

Answer 1

In the Windows firewall, create an allow rule on the incoming rules.
1560/TCP is indicated in the "Protocols and Ports"
tab. In the "Region" tab, specify the local address of the server
. In the remote address field, specify only the addresses of the required PCs.
In "Advanced" specify what is valid for all profiles.
As a result, the port will be available only locally and for all IP addresses specified in the Remote IP address field

Answer 2

Complete madness, open a local network to the Internet.
