Industrial Ethernet firewall/NAT router

Nasz firewall/NAT router skutecznie integruje równoważne IP podsieci

Industrial routers typically support a wide range of functions. Depending on the respective application, however, only a few of these features are actually required. Focusing on the essentials is essential if the amount of work required for IP integration of machines in higher level networks is to be minimised.
So you do not have to forego a high degree of network security, we have specifically designed our new firewall/NAT router IE SR-2GT LAN FN for applications in which the priority is on network security and network address translation (NAT). By means of the integrated stateful packet inspection firewall with flexible 2-way packet filtering (WAN/LAN inbound and outbound), the router reliably protects industrial IP networks. Via the functions 1:1 NAT and IP forwarding/virtual mapping, you can flexibly integrate equivalent IP subnetworks without needing to adjust the machine network in a higher level production network.

The new router model is the most efficient choice for integrating systems with the same IP address space.

 Gleichteile-Serienmaschinen mit jeweils identischen IP-Adressen in ein bestehendes Produktionsnetzwerk integrieren – das gelingt besonders einfach und sicher mit dem neuen Weidmüller Firewall/NAT-Router
Integrate common-part series machines, each with identical IP addresses in an existing production network – this works especially simply and reliably with the new Weidmüller firewall/NAT router








Outstanding performance

Gigabit Ethernet interfaces enable a very high data throughput. Reliable network security

is assured by the stateful packet inspection firewall with flexible 2-way packet filtering for

bidirectional data traffic monitoring.

Product advantages


Optimised network infrastructure

IP-routing provides controlled transmission of data traffic between subnetworks. At the same time, segmentation into subnetworks reduces network loads.

Easier configuration

IP addresses are virtually implemented by 1:1-NAT. Series machines with identical IP configuration can now be operated in parallel and integrated into higher-level networks - without the need to assign individual IP address ranges to each machine.

High degree of network security

The integrated firewall with extensive configurable

filter functions recognises legitimate data traffic and prevents network access by unauthorised data.
