    Use this in a live application to limit publishing to allowed IP addresses. IP list is set in Application.xml property.
    Code:
    package com.wowza.wms.plugin.collection.module;

import com.wowza.wms.amf.*;
import com.wowza.wms.client.*;
import com.wowza.wms.module.*;
import com.wowza.wms.request.*;

public class ModuleOverridePublishRestrictIP extends ModuleBase {
	
	public void publish(IClient client, RequestFunction function,
	        AMFDataList params) {
		getLogger().info("Overriding Publish");
		
		boolean reject = true;
		String[] ipList = null;
			
		try 
		{ 
		ipList = client.getAppInstance().getProperties().getPropertyStr("ipList").toLowerCase().split(",");
		String clientIP = client.getIp();
		for (int i = 0; i < ipList.length; i++)
		{ 
			if (clientIP.equalsIgnoreCase(ipList[i].trim()))
			{
				reject = false; 
			}
		} 
		} 
		catch(Exception ex)
		{
			reject = true;
		}
		if (reject)
		{	
			sendClientOnStatusError(client, "NetStream.Publish.Denied", "The publisher's IP was rejected");
			getLogger().info("Client Rejected. IP: " + client.getIp());
		} 
		else
		{	
			invokePrevious(client, function, params);
		}		
	}
	
	public void releaseStream(IClient client, RequestFunction function, AMFDataList params)
	{
		getLogger().info("Overriding streamRelease");
		
		boolean reject = true;
		String[] ipList = null;
			
		try 
		{ 
		ipList = client.getAppInstance().getProperties().getPropertyStr("ipList").toLowerCase().split(",");
		String clientIP = client.getIp();
		for (int i = 0; i < ipList.length; i++)
		{ 
			if (clientIP.equalsIgnoreCase(ipList[i].trim()))
			{
				reject = false; 
			}
		} 
		} 
		catch(Exception ex)
		{
			reject = true;
		}
		if (reject)
		{
			sendClientOnStatusError(client, "NetStream.Publish.Denied", "The publisher's IP was rejected");
			getLogger().info("Client Rejected. IP: " + client.getIp());
		} 
		else
		{			
			invokePrevious(client, function, params);	
		}		
		
	}
	
}
    A compiled version of this module is included in the Wowza Modules Collection. Download and unzip the collection, then copy /lib/wms-plugin-collection.jar from the package to the Wowza /lib folder. Then restart Wowza.

    Add the following module to the Modules list of your Application.xml.

    Code:
    <Module>
	<Name>OverridePublishLimitIP</Name>
	<Description>Override publish</Description>
	<Class>com.wowza.wms.plugin.collection.module.ModuleOverridePublishRestrictIP</Class>
</Module>
    And add this Property to the Properties section of your Application.xml, below the Modules list:

    Code:
    <Property>
	<Name>ipList</Name>
	<Value>127.0.0.1</Value>
</Property>

      You need the Wowza IDE:

      Hi,

      Its been long time that i do not post around here.
      But, seen this, i would like to know IF there is a easy way to instead of limiting a given xml IPaddress, but to limit encoder(s) sessions to be only 1 (first started for example)

      * If an encoder is already connected/encoding then to denny connections from all the others, no matter the stream name. *

      Is it possible to do this with an add-on on the application.xml and using the collection already?

      Thank You

      You should be able to adapt ModuleLimitConnectionsToApplication from the module collection to do what you need:
