Features:
- GSM, UMTS, and HSPA+ transport carries IP traffic from Ethernet automation devices.
- IPsec VPN, stateful firewall, and NAT functions process traffic before it reaches the mobile network.
- A two-port local switch, SMA antenna socket, digital input, and digital output share one compact router.
Ethernet devices connect to the two internal ports of Siemens 6GK5874-3AA00-2AA2 before traffic is routed to the cellular interface.
Security rules in 6GK5874-3AA00-2AA2 determine which addresses, services, and VPN flows may cross between the local and mobile networks.
Management and diagnostics for 6GK5874-3AA00-2AA2 use its web interface, HTTPS, SNMPv1, email traps, and time synchronization.
The Siemens 6GK5874-3AA00-2AA2 SCALANCE M874-3 3G Router may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Cellular Network Path
- Radio families: The WAN path accepts GSM and UMTS networks.
- Packet services: GPRS, eGPRS, and HSPA+ provide the documented mobile data services.
- Antenna connection: The external radio path uses a 50-ohm SMA socket.
- National approval: The installed radio configuration must follow approvals for the country of operation.
Address Translation and Forwarding
- Masquerading: NAT can present internal addresses through the routed external connection.
- Fixed mapping: 1:1 NAT maps a selected internal and external address pair.
- Service exposure: Port forwarding directs defined incoming services to an internal endpoint.
- Traversal: NAT traversal supports applicable protected communication across translated paths.
Protected Traffic Processing
- Firewall state: Stateful inspection evaluates packets against the active connection state.
- Packet filter: Rules can permit or reject traffic by the configured packet criteria.
- VPN mode: IPsec is available in both tunnel and transport modes.
- Access control: Password protection and HTTPS restrict management access to the router.
Configuration and Diagnostic Channels
- Browser setup: Web-based management provides the configuration interface.
- SNMP check: SNMPv1 exposes supported status information to a management station.
- Email event: Configured traps can be sent by email for diagnostic notification.
- Clock service: NTP aligns the router clock used by time-dependent records and services.
