TP-Link TL-R470T+ Load Balance Broadband Router

As I mentioned in previous article, I am currently with two providers: a place with optical fiber connection and the Vivo Internet Fixed, ADSL connection. In both cases, the plan is 10 Mbps de download, but uploading is different: 2 Mbps only in the optical fiber and 600 Kbps no ADSL.

The choice of two providers was by fiber optic provider account not be there very reliable, having come to go two days without connection because of an equipment problem or something. As I need the Internet for work, I thought it best to hire a second connection and stick with the two, so the chance of both fail at the same time is very small. Furthermore, I have twice the speed in applications that allow you to split traffic, as torrents and downloads from multiple sources, for example.

Initially I intended to do load balancing with ASUS RT-AC68U Dual Band Gigabit Router 802.11ac Wireless-AC1900, because it has an option for it. But, this part of the firmware still has many bugs and still can not use it without going through anger. The router works fine with a single connection, It is one of the best in the market, but for two connections it serves no.

Early on, to set up two connections to the ASUS RT-AC68U, enough both are connected to any network equipment could access anything. It only worked when one of the two was inactive. I ended up leaving it aside and got the TP-Link TL-R470T+ Load Balance Broadband Router, which is a specialized router Load Balancing, supporting up 4 simultaneous connections, and allowing set them freely for load balancing or to be activated only when the primary connection fails.

TP-Link TL-R470T+ Load Balance Broadband Router

The TP-Link TL-R470T+ Load Balance Broadband Router It has several hardware upgrades, I got the latest (v4) and installed the latest firmware. The low cost I thought it is reasonable enough. Load balancing is efficient and can take into account the speed of each link (It is configurable). Are 5 portas Ethernet de 10/100Mbps, one of which is exclusive to WAN port, another door is unique to LAN, and the other three can be configured for WAN or LAN.

With the TP-Link TL-R470T+ It can assign specific IP addresses to specific MAC address in the DHCP, Clone MAC Address, control traffic on each switch port, create VLANs, ultimately, all the basics and even a little more. It can create rules to redirect ports or port ranges for specific IPs, valid for a single WAN or all of them, para TCP, UDP ou ambos, and the outer door and the inner may be different. The resource “Port Triggering” It is also present and is quite flexible.

The traffic control, on the other hand, It is just basic. He is not a fact of QoS, just a feature that lets you create rules to ensure a minimum flow or limit the maximum flow rate to an IP or an IP group. You can not use QoS according to the protocol or service, What is a shame. On ASUS RT-AC68U QoS is much more complete. Another feature of TP-Link TL-R470T+ It is a session border, Also IP or IP group.

In load balancing is that the TP-Link TL-R470T+ shines. Here you can set various types of exceptions. For example: I have set up a group with my video games and smart TVs and they always use the fiber optic connection, except if it is not available. In the case of video games (Playstation 3 and Playstation 4), the idea is that they will benefit from lower latency fiber optic connection, which is essential for online games. No caso das Smart TVs, it is only because the higher upload the optical fiber decreases the chance that the TCP acknowledgment packets from getting tangled and lower the quality of streaming Netflix. Other equipment use both connections normally in a balanced way, transparently to the user. Routing rules can be created based on source IP, Destination IP, port or range of source ports, port or destination port range, for protocol TPC, UDP, TCP e UDP ou ICMP. Okay flexible.

There is also a firewall with protection for various types of attacks, divided between attacks flood, and packet anomaly attacks. There MACs filters, filtros de URLs, filtros Web (Java, Activex, Cookies), access rules for times, services, IPs, ultimately, okay too full. UPnP está presente, but it seems a bit flawed. It is common to see the empty list, as if the application had tried, but failed. Dynamic DNS services like DynDNS and No-IP are supported, but there is currently a bug terrible this service, I will talk later.

The statistics are decent, showing traffic over WAN, por IP local, in terms of packets or bytes. Can you consult the complete NAT table, sometimes thousands of entries. It is only missing forms to see such measures graphically, como as do ASUS RT-AC68U.

Another highlight of the TP-Link TL-R470T+ It is that every setting is applied immediately, without restarting. Really, It gives everything to change without restarting. That's a huge advantage. On ASUS RT-AC68U any minor change requires a reboot, often full, which takes a few minutes. On TP-Link TL-R470T+ everything is immediate and imperceptible to anyone who is using the network.

But what I found missing in TP-Link TL-R470T+ It was a SSH server and secure web interface through HTTPS. It has only an unsecured web interface (HTTP) e servidor Telnet. It can allow remote administration, any IP or specifically choosing tracks or specific IPs, then it is expected that SSH and HTTPS were present. Administer remotely via HTTP and Telnet is a serious security problem. Telnet is pretty basic, nothing bash, only one shell minimalistic with few options and somewhat confusing.

Do not also present in TP-Link TL-R470T+ Gigabit Ethernet ports, it will only be a problem if your connections are more than 100 Mbps. Well I would like to have this problem :). There is also no support for IPv6, which is a problem if your provider offers IPv6, which is not my case.

My first weeks with the TP-Link TL-R470T+ were poor. The web interface simply “bugava” all within a few hours / days of use. The only way to re-use it was restarting, what it had to be done via Telnet, or removing and replacing the power cord. TP-Link's support did not help, only concluded that it was a hardware problem and requested to make RMA, which I refused because searching the web found many people with the same problem.

I ended up leaving TP-Link TL-R470T+ sideways, I returned to the ASUS RT-AC68U and after several tests I realized that it worked in the Dual WAN “Port Triggering” was disabled. It's a bug. Port Triggering is enabled Dual WAN does not work. Warned the support of ASUS, but so far nothing correction. So I tried to give up “Port Triggering”, which in any case only use for the service to work in Identd mIRC. But then I discovered that the ASUS RT-AC68U tem outros bugs no Dual WAN. Often the connections fail, Web pages do not load, etc. Furthermore, the watchdog does not work with load balancing. He just realizes that a connection is not working if the connection actually fall, if the connection is active but not working (Provider fell link, for example) he even notices.

And while I ventured me with the Dual WAN “buggy” from the ASUS RT-AC68U, some users TP-Link TL-R470T+ They found that the problem of wage interface is related to the dynamic DNS service. Disabling the service he no longer hangs. TP-Link is already aware of the problem and says it will be fixed with a new firmware, but so far nothing.

Now I'm using TP-Link TL-R470T+ again, without any locking. For now I had to give up his dynamic DNS. I have the same service in Synology America DiskStation 2-Bay Diskless Network Attached Storage (DS214play) and no NS-K330 - USB Server / NAS / FTP / SAMBA / Print / UPNP / Sharing + De BitTorrent client, but the TP-Link TL-R470T+ It is more interesting because it lets you update different addresses for each WAN. Now is hope that the TP-Link logo correct the problem.

    Skooter, I wanted to leave a tip here, suddenly have trouble you will already have an idea of ​​how to solve.

    A client of mine bought a D-Link dual wan and was having trouble accessing banks.

    I found that the problem is because as the bank uses secure connection, and the attempt to access it through a session with two real ip addresses (hence the name balance, rsss) It is considered an attack or an attempt to circumvent the bank's system.

    To solve this you need to put a rule in the router so that it always use only one of the Wan certain ports to access secure sites (HTTPS/443).

      Ola Lincoln,

      I got to use such a rule for some time. But just after opting to enable the “Enable Application Optimized Routing”. As I understand it, with this option on all of the same local IP traffic to the same remote IP out the same WAN. Thus the rule is not necessary. The advantage is that it has other sites, including some that use HTTP / 80, who also do not like to connections coming from more than one IP. Some forums deslogam the user in these situations.

      The downside is that downloads with accelerator, but which have a single server, They end up being downloaded with a single WAN. The Speedtest will also be limited in WAN that chose. Many people turn off the option to be able to see the speed-up in the Speedtest. But in practice I do not see much difference.
