Provides SNMP version translation in intranet and across firewalls


Network Management Systems (NMS) using the Simple Network Management Protocol (SNMP) are widely deployed to manage today’s corporate networks. As the three versions of SNMP (v1,v2c and v3) can all be found in these heterogeneous networks, sometimes there is a mismatch between the versions supported by the NMS and those supported by the device. In addition, firewalls which break up these networks into zones with varying levels of security are often set up to block UDP/SNMP traffic. This makes the resources in the cordoned off zones, invisible to the NMS. 

SimpleSnmpProxy™ is an easy-to-deploy, software solution that provides version translation, event forwarding, and management visibility to firewalled resources. It provides protocol translation between the various versions of SNMP allowing an SNMPv1 NMS to manage a SNMPv2c or v3 device or SNMPv3 application to manage a SNMPv1 device. It also allows SNMP traps, informs, syslog, netflow and slow packets to be forwarded both in the intranet and from restricted zones to one or more specified managers/collectors. In addition, it securely provides management visibility to the resources within cordoned-off zones like the DMZ. Your existing NMS can now be leveraged to manage devices with unsupported SNMP versions and critical resources like eCommerce servers within the DMZ without compromising security.

SimpleSnmpProxy is made up of “iProxy” that runs on intranet side. It does the protocol translation and demultiplexing when communicating with intranet devices. For managing devices in the restricted zone, the “iProxy” communicates over an encrypted TCP connection with a “zProxy” that runs within the restricted zone. Only a single port/rule is required to be added to the firewall to enable UDP based management traffic like SNMP, NetFlow, sFlow and sysLog to be securely forwarded to the management and collector systems in the intranet. Support for IP Mapping, where virtual IPs are added to the iProxy, is also available.
