ESR service router lineup update: introducing a new model

27 February 2026

ESR-3150

 

We're steadily updating our ESR series of service routers, replacing previous-generation models with new ones. Following ESR-3250 and ESR-3350, the ESR-3150 router has been launched into mass production. This equipment is intended for enterprise and government networks, as well as industrial sites.

 

“The increasing load in enterprise and carrier networks places higher demands on routing performance and network infrastructure stability. ESR-3150 is a planned update of the Eltex service router lineup and the successor to ESR-3100. This model is designed for a variety of application scenarios — from enterprise networks to distributed infrastructures with a margin for future load growth.”

 

– Aleksandr Sidorov, Head of the ESR Router Department at the Eltex Service Center

 

The ESR-3150 key benefit is its support for DMVPN, the highly-demanded technology for securely deploying distributed networks and connecting remote branches. The device can act as a Hub.

 

The router supports Active/Standby clustering for redundancy. Additionally, the NAT mechanisms are available for access to external networks, and RemoteAccess through WireGuard and IPsec allows remote clients to safely access the network.

 

ESR-3150 is used for deploying MPLS networks with L2VPN and L3VPN support. It also functions as a firewall supporting Application Control, IPS, and Web-filtering based on Kaspersky Lab signatures. Starting with firmware version 1.40, ESR-3150 can act as a Certification Authority (CA) for IPsec connections.

 

The hardware platform has 8×1G Combo ports and 4×10G SFP+ ports, Firewall throughput reaches 21.69 Gbps, IPsec VPN – 3.35 Gbps (IMIX).
