Access for specific IP adresses or IP ranges

[acsgc]

Hey,

is it possible to specify an IP adress or adress range for the VNC Server to accept connections only from these IP adresses or ranges?

yes, that's possible.
There's a registry key (REG_SZ) called HKLM\Software\ORL\WinVNC3\AuthHosts.
See http://www.realvnc.com/products/free/3. ... nc.html#11

The AuthHosts setting is, unlike the other settings, a REG_SZ string. It is used to specify a set of IP address templates which incoming connections must match in order to be accepted. By default, the template is empty and connections from all hosts are accepted. The template is of the form:
+[ip-address-template]
?[ip-address-template]
-[ip-address-template]
In the above, [ip-address-template] represents the leftmost bytes of the desired stringified IP-address. For example, +192.168 would match both 192.168.12.10 and 192.168.14.2. Multiple match terms may be specified, delimited by the ":" character. Terms appearing later in the template take precedence over earlier ones. e.g. -:+192.168: would filter out all incoming connections except those beginning with 192.168. Terms beginning with the "?" character are treated by default as indicating hosts from whom connections must be accepted at the server side via a dialog box. The QuerySetting option determines the precise behaviour of the three AuthHosts options. Local machine-specific setting.

Hello

I search the other way - to allow a client to connect only to server in a specific ip range.
The servers can accept connections from many other clients.

Is this possible?

You might be able to use mslogon and control who can access servers by specific usernames as well but other then the above methods that is about it..

Note: You will need to use uvnc as a service to use the authhost option..
