Configurations to cover the following :

1. When traps are generated by the Agent(End Device), The Agent's trap destination be configured with ip Address of the SNMP Proxy Forwarder. But, The Actual Manager to which the snmp proxy forwards, must know the actual source (original ip of the node that triggered the trap) of the incoming traps.

2. When polling the devices for some specific OID,
   - Polling (snmpget, snmpwalk, etc.) request from a Manager Server, be targeted to actual end device, But the request be routed through the snmp proxy server.
   - The actual end device to receive the poll request as if originating from snmp proxy ip.
   - Response to be routed back to snmp proxy server, proxy forwards it to the Manager Server.
   - The Manager to see the response originating from the End Device and not from the snmp proxy.
   - The polling to meet at least 100 end devices. And, Manager polls to these 100 end devices & requests to be routed through the snmp proxy.
