3225
Summary
- // if you see it open
- RFC 3821 requires FCIP entities to implement cryptographically protected authentication, data integrity, and confidentiality features. Restrict connections to authorized FCIP peers.
- // common applications
- Connecting Fibre Channel storage area ne FCIP peer connections transporting Fibre Channel traffic over IP networks; port assignment alone does not confirm observed application traffic.
About port 3225.
IANA assigns TCP port 3225 the service name fcip-port for FCIP. RFC 3821 defines FCIP as a mechanism for connecting Fibre Channel storage area network islands over IP networks. The evidence establishes the protocol and assignment, but does not establish whether a particular host uses the port or whether it should be publicly reachable.
RFC 3821 describes FCIP links as using at least one TCP connection, with multiple connections permitted. FCIP carries Fibre Channel frames between storage network segments; it is intended for configured peers that extend a Fibre Channel fabric across an IP network. A connection on this port is consistent with FCIP, but the port number alone does not confirm the application.
The RFC’s security model requires cryptographic peer authentication, data integrity, and confidentiality features. Because this protocol connects storage fabrics, allow access only between authorized FCIP peers and apply the RFC’s security mechanisms. The available evidence does not support claims about prevalence, typical devices, malware association, or a general public-internet access policy.
