Reset Method (IPFilters)

Summary

Resets the collection to its default settings.

Syntax

C++

public void Reset()

Public Sub Reset()

public: 
void Reset();

Remarks

Reset is performed on the parameters stored in memory. To change the file settings call the SetIPFilters method.

The default collection contains a single filter that allows connections for the entire IP address range.

If the method fails, an error is raised. For more information, refer to the Error Codes.

Example

using Leadtools; 
using Leadtools.MediaStreaming; 
 
 
public Server _server = null; 
public bool _result = false; 
 
public void SetLocalNetworkFilterExample() 
{ 
   try 
   { 
      // this routine will set up an IP filter that only allows local network connections 
 
 
 
      string ipfirst = ""; 
      string iplast = ""; 
 
      // create an instance of the server object 
      _server = new Leadtools.MediaStreaming.Server(); 
 
      // retrieve a copy of the IP Filters 
      IPFilters filters = _server.GetIPFilters(); 
 
      // create a full range blacklist 
      // equivalent to filters.Add("0.0.0.0", "255.255.255.255", false); 
 
      // create a full range whitelist 
      filters.Reset(); 
 
      // invert the single whitelist filter to create the blacklist 
      filters.Remove(0); 
 
      { 
         // obtain the server's IP address and create the filter range 
         NetworkProperties props = _server.GetNetworkProperties(); 
 
         string str = props.ActualIPAddress; 
         int n = str.LastIndexOf("."); 
 
         ipfirst = str.Substring(0, n) + ".0"; 
         iplast = str.Substring(0, n) + ".255"; 
      } 
 
      // now add a filter to allow for the local network IP range 
      filters.Add(ipfirst, iplast, true); 
 
      // copy the filters to the server 
      _server.SetIPFilters(filters); 
 
      _result = true; 
   } 
   catch (Exception)

      _result = false;
