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.
Features
- SNMPv1/v2c/v3 operations with built-in protocol and transport translation capabilities
- SNMPv3 USM supports MD5/SHA/SHA224/SHA256/SHA384/SHA512 auth and DES/3DES/AES128/AES192/AES256 privacy crypto algorithms
- Forwards SNMP commands and notifications
- Maintains multiple independent SNMP engines and network transports
- Split client and server parts interconnected through encrypted TCP links
- Flexible SNMP PDU routing
- Extension modules supporting SNMP PDU filtering and on-the-fly modification
- Supports transparent proxy operation (Linux only)
- Works on Linux, Windows and OS X
