TCP 3260
Synopsis
- TCP port 3260 is the default port for the iSCSI (Internet Small Computer Systems Interface) protocol used by initiators to connect to storage targets.
- Operating systems: Microsoft Windows uses the Microsoft iSCSI Initiator and Windows Server iSCSI Target on 3260; Linux commonly uses open-iscsi (initiator) and LIO/targetcli or tgt (target); FreeBSD and TrueNAS expose their iSCSI service on 3260.
- Virtualization platforms like VMware ESXi/vSphere use the built-in iSCSI software adapter on 3260 to connect to SAN storage.
- Storage arrays and NAS appliances such as NetApp ONTAP, Dell EMC Unity/VNX, HPE 3PAR/Alletra, Synology, and QNAP export iSCSI LUNs over 3260.
- Software SANs including StarWind Virtual SAN, Openfiler, and TrueNAS CORE/Enterprise provide iSCSI targets listening on 3260.
- Cloud-connected products like AWS Storage Gateway expose iSCSI targets to on-prem hosts over TCP 3260.
- Security: publicly exposed iSCSI on 3260 is sometimes targeted for data theft or ransomware staging when authentication (e.g., CHAP) is weak or misconfigured, since attackers can enumerate and mount raw LUNs.
