Where an industrial NAT router helps.
Keep machine IP addresses unchanged
Keep existing IP settings, even when machines use the same address. Connect each separate machine LAN through its own configured router.

Example addresses
Connect machines across different subnets
Connect PLCs and HMIs to factory SCADA or MES. Use routing where addressing and return paths allow; configure NAT only when required.
10.20.30.0/24R2111Routing · NAT if needed192.168.1.0/24Example addresses
NAT translates addresses; firewall rules permit traffic. Keep duplicate-IP machines in separate LANs: NAT cannot resolve duplicate addresses within one LAN. Verify firmware support, return paths and application protocols. RCMS management needs an internet path and the applicable service, activation and terms.
TCP port mapping example
For a required HTTPS service, configure TCP 8443 at the factory-side router address to reach TCP 443 on the machine device. Configure and verify the mapping, return path and firewall rules for the supplied firmware.
Start with a focused NAT evaluation.
Map the address spaces
Record equipment and site subnets, gateways, service ports and required traffic direction.
Allow one required service
Configure a narrow port mapping and source-access rules for an authorised client.
Check allowed and blocked traffic
Verify the application session, denied connections, discovery behaviour and configuration after a restart.
Plan remote operations
Confirm the internet path and applicable RCMS / remote-access service before wider deployment.

Frequently asked questions
Can I connect machines without changing their IP addresses?
Yes, with the required NAT or port mapping configured. Keep machines with identical IP addresses on separate LANs, using one configured R2111 per machine network. Devices on the same LAN still need unique addresses. Check firmware support, return paths and your application protocol.
Can R2111 connect devices in different subnets?
Yes, when routing and return paths are configured. Use NAT where address constraints require it, and firewall rules to allow only the traffic you need. Verify that your application protocol works across the connection.
Does R2111-NU need a SIM card?
No. R2111-NU is a wired Ethernet router with no built-in cellular modem. It uses an Ethernet uplink; choose a 4G or 5G router if your site needs cellular connectivity.
Can I use R2111-NU for remote PLC maintenance?
Yes, with an internet-connected wired uplink and a supported VPN or RCMS remote-access setup. Confirm the equipment you need to reach, firmware support and any required service activation or subscription.
