SNMP Proxy Forwarder

The SNMP Proxy Forwarder tool works as an application-level proxy with a built-in SNMP message router. SNMP forwarder design features split client/server operation that promotes having one part of the system in DMZ while other part is facing the Internet. Message routing can be programmed via a declarative mini-language.

Typical use case for an SNMP proxy is to work as an application-level firewall or a protocol translator that enables SNMPv3 access to a SNMPv1/SNMPv2c entity or vice versa.
