ER605 v2 is the first SMB router that supports 4G/3G USB Modem function, and adds the new features such as IPTV, DHCP Option 67 and DHCP Relay. With optimized chip scheme and improved processing performance, the ER605 v2 supports more concurrent session and higher IPsec VPN throughput compared to v1. Let's read on to learn more about this new product!

1. Appearance

The overall appearance and size of ER605 v2 are almost the same as ER605 v1, the main difference is that ER605 v2 adds a USB 2.0 interface and a USB LED indicator.

2. Hardware features

• Five Gigabit RJ45 Ports: 1 Fixed WAN port, 2 Changeable WAN/LAN ports and 2 Fixed LAN ports.

• Up to 3 WAN Ports: support load balance feature, which raises the utilization rate of multi-line broadband.
• One USB WAN Port for Mobile Broadband: Mobile broadband via 4G/3G modem is supported for WAN backup.*
• Durable metal casing and desktop/wall mounting design, suited for different environments.

Note: The actual rate of the USB WAN port is affected by the rate allocated by the Internet Service Provider and the performance of the 4G/3G USB Modem.

3. New features

Compared to the first hardware version of ER605, ER605 v2 has added the new features below.

(1) USB Modem

• Support DHCP Relay, which can be used as DHCP Server to assign IP addresses to clients on different network segments.

(5) Encryption algorithm of IPsec VPN

ER605 v2 adds SHA2 encryption to the IPsec VPN function and supports IKEv2, making VPN communication more secure. ER605 v1 will add this function in the next firmware update.

4. Comparison to ER605 V1

Due to the use of a new chip solution, ER605 v2 has significantly improved the maximum number of concurrent connections and IPsec VPN throughput compared to v1. Make v2 support more clients and a more powerful VPN forwarding function. The following is a detailed parameter comparison.

5. Application Scenarios

• Used in conjunction with LTE 3G/4G USB Modem, it can support WAN backup. It is suitable for scenarios where WAN port link backup is required but there is only one wired link, which can improve the stability of the network.

• Ensure the security of data transmission between multiple sites. One-click auto IPSec VPN greatly simplifies VPN configuration and facilitates network management and deployment. It also secures and encrypts private site-to-site data communications traveling over the internet.

• Suitable for home users with computers and TVs, able to use the computer to surf the Internet while watching TV. The increase of IPTV functions can provide users with high-quality digital media information services.
