10/100 firewall with four-port switch

The Linksys BEFSX41 combines a cable/DSL firewall router and a four-port 10/100 switch in one desktop appliance. It inspects inbound traffic for Ping of Death, SYN Flood, Land attacks and IP spoofing while providing URL and time filtering plus Java, ActiveX and cookie blocking. Up to two IPSec VPN tunnels allow remote access for branch offices or teleworkers. Configuration is handled through a web browser from any connected PC.

Small offices needing basic VPN

This unit suits small businesses that want a dedicated DMZ port and simple browser-based management without a separate switch. It is not for networks that require Gigabit throughput, more than two concurrent VPN tunnels, or advanced intrusion-prevention signatures. Buyers needing wireless connectivity or deeper packet inspection should look elsewhere.

Two concurrent IPSec VPN tunnels

The specification that decides fit is the limit of two simultaneous IPSec tunnels for site-to-site or remote-access VPNs. If your deployment needs more than two tunnels, this appliance will not meet the requirement. All other features — 10/100 ports, DMZ, DoS protection, content filtering — support that core capability.

Questions about this item

How do I confirm the BEFSX41 is working after connecting it?

Check that the Power LED stays solid green, the Diag LED is off, and each LAN port shows Link/Act and 100 LEDs lit for active 100Mbps full-duplex links.

What ships in the box and what must I supply?

The package includes the BEFSX41 unit, a resource disk, one RJ45 cable and the power adapter; you must provide the broadband modem and any additional Ethernet cables for the four LAN ports.

Which BEFSX41 version should I choose for a small office needing a DMZ and two VPN tunnels?

This single model provides a dedicated DMZ port, 10/100Mbps WAN and four LAN ports, and supports up to two IPSec VPN tunnels, matching those requirements.
