        More Information

        Overview Manuals Network Zones Firewall & NAT VPN Setup Power & C-PLUG

        Features:

        • Two separate RJ45 ports divide internal automation traffic from the external network path.
        • Stateful firewall, IPsec VPN, routing, NAT/NAPT, DHCP, and SysLog functions share one security platform.
        • A C-PLUG slot preserves configuration data independently of the replacement hardware.
        Siemens 6GK5612-0BA10-2AA3 places packet inspection between two physically distinct Ethernet zones.

        Only traffic permitted by the configured firewall, routing, address-translation, or VPN rules passes across that boundary.

        Its cabinet-mounted IP20 enclosure receives 24 V DC power and retains exchangeable configuration data on an optional C-PLUG.

        Apter Power provides documentation, quotations, and selection support for Siemens 6GK5612-0BA10-2AA3.

        Internal and External Port Roles

        • Internal port: This RJ45 connection faces the protected automation-network segment.
        • External port: The second RJ45 connection faces the upstream or untrusted network segment.
        • Link rate: Each connection negotiates 10, 100, or 1000 Mbit/s Ethernet.
        • Traffic path: Packets cross between ports only through configured security and routing rules.

        Packet Control and Address Translation

        • Stateful inspection: Return traffic is associated with an allowed session instead of being judged as an unrelated packet.
        • NAT function: One address can be translated when traffic moves between the internal and external networks.
        • NAPT function: Port translation distinguishes multiple sessions that share a translated address.
        • Log output: SysLog records selected security and communication events for diagnosis.

        Encrypted Tunnel Parameters

        • Peer identity: The configured remote endpoint must match the address or identity expected by the tunnel.
        • Authentication: Pre-shared keys or certificate settings must agree at both VPN peers.
        • Protected networks: Local and remote subnet definitions determine which packets enter the tunnel.
        • Tunnel capacity: The security module supports up to 128 configured VPN connections.

        Supply and Configuration Retention

        • Supply input: The module accepts 24 V DC within the documented 19.2 to 28.8 V range.
        • Current demand: The source and wiring must allow for the documented maximum current of 0.5 A.
        • Configuration media: A C-PLUG can hold the device configuration separately from the base hardware.
        • Cabinet requirement: The IP20 enclosure requires installation inside a suitable protected cabinet.
        Description
        Siemens 6GK5612-0BA10-2AA3 is a SCALANCE S612 security module that creates a controlled boundary between an internal automation network and an external network. Its two gigabit-capable RJ45 ports keep those zones physically distinct while the module evaluates the traffic crossing between them.

        At the packet boundary, 6GK5612-0BA10-2AA3 applies stateful firewall rules and can translate addresses through NAT or NAPT. Router and DHCP-server functions organize the permitted paths, while SysLog messages provide a record of security and communication events.

        Encrypted site or service connections on 6GK5612-0BA10-2AA3 use IPsec VPN tunnels, with configuration determining the peers, authentication data, and networks allowed through each tunnel. The documented capacity supports as many as 128 VPN connections without treating ordinary routed traffic as encrypted traffic automatically.

        Power for 6GK5612-0BA10-2AA3 enters through the 24 V DC terminal, and a C-PLUG can retain configuration data for controlled device replacement. The IP20 enclosure is installed inside a suitable cabinet, where the documented temperature limits apply to the complete security module.

        Technical notes
        For Siemens 6GK5612-0BA10-2AA3, the internal and external RJ45 ports represent different security zones. Firewall, NAT, routing, and VPN parameters must follow that port assignment.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        What happens if the internal and external cables are reversed on Siemens 6GK5612-0BA10-2AA3?
        Reversing the two zone cables on Siemens 6GK5612-0BA10-2AA3 applies firewall, routing, and NAT rules to the wrong network sides and can block intended traffic.
        Why can 6GK5612-0BA10-2AA3 pass local traffic but fail to establish an IPsec tunnel?
        For 6GK5612-0BA10-2AA3, compare peer identity, pre-shared key or certificate settings, protected subnets, time, and upstream reachability at both VPN endpoints.
        How should a DHCP conflict caused by 6GK5612-0BA10-2AA3 be avoided?
        Enable the 6GK5612-0BA10-2AA3 DHCP server only on the intended segment and ensure no other server distributes overlapping addresses there.
        What should be checked when NAT rules on Siemens 6GK5612-0BA10-2AA3 do not return traffic?
        On Siemens 6GK5612-0BA10-2AA3, verify rule direction, translated address, gateway routes, stateful firewall permission, and the remote device return path.
        Can the C-PLUG alone power or license 6GK5612-0BA10-2AA3?
        No. The C-PLUG on 6GK5612-0BA10-2AA3 stores configuration data; the module still requires its normal 24 V DC supply.
        Which evidence helps diagnose intermittent firewall drops on 6GK5612-0BA10-2AA3?
        Use the 6GK5612-0BA10-2AA3 port status, firewall counters, VPN status, and SysLog records to identify the rule or link involved.
