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.

 

β€œThe 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 β€” 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 8Γ—1G Combo ports and 4Γ—10G SFP+ ports, Firewall throughput reaches 21.69 Gbps, IPsec VPN – 3.35 Gbps (IMIX).
