ProductLinksys Gigabit VPN Router (LRT214)   [Website]
SummaryVPN router with Gigabit ports and hardware DMZ port supporting PPTP, IPsec and OpenVPN tunnels
Pros• Flexible VPN solutions for IPsec, SSL, and PPTP
• Integrated with OpenVPN for SSL
• Easy to use firewall
Cons• Software and manual "glitches"
• Low SSL VPN Client to Gateway throughput

Early in 2013, Cisco sold its Linksys brand to Belkin, with the deal completing in March of 2013. In November 2013, Belkin relaunched a small business line of Linksys products, including multiple unmanaged switches, IP cameras, access points and two VPN routers.

The LRT214 Gigabit VPN Router and LRT224 Dual WAN Gigabit VPN Router are nearly identical, sharing the same physical design and components. The difference is that one port on the LRT214 is a DMZ only port, while the same port on the LRT224 is a WAN/DMZ port. This makes the LRT214 a single WAN router and the LRT224 dual WAN. Linksys sent the LRT214 for review, so that's what I'm looking at today.

The LRT214 is housed in a metal case measuring 5.25"W x 7.75"D x 1.75"H. The power supply is external and cooling is passive, so the device runs silently. There are two slots on its bottom for wall mounting. Physically, the LRT214 is very similar to the original Linksys RV042 I reviewed in 2007.

The front of the LRT214 is simply the Linksys name, as shown at the top of this review. On the top of the front edge are the indicator LEDs shown below. I like the VPN light, which indicates the status of the first Gateway-to-Gateway IPsec tunnel. However, I noticed if you use the Keep Alive feature in your IPsec tunnel config, the VPN LED will remain lit even if the tunnel is down.



The rear panel of the LRT214 has the Gigabit Ethernet ports, shown below.

As mentioned in the introduction, the LRT214 and LRT224 share the same components. When I opened it up to take inventory, I was struck at the board's uncanny resemblance to the Cisco RV042G board. See for yourself in the side-by-side composite below.

Underneath the lower heatsink is a Cavium CN5020 CPU running at 300MHz. The LRT214 has 32 MB of Flash memory and 128 MB of RAM. Under the upper heatsink is a Broadcom BCM53125M 7 port Gigabit switch. A BCM54612 Gigabit Ethernet transceiver sitting to the heatsink's right helps out the switch.

The LRT214/224's key components are summarized in Table 1, with the Cisco RV042G and RV042 v3's for comparison. It appears that the LRT214 is hardware-wise a Cisco RV042G clone with a dual-core vs. single-core CPU.
