 Hi guys, welcome back to my YouTube channel. This is Daniel Rosal here. I want to do a video showing the configuration in the TP-Link ER605 OMAD, a gigabit multi-wan VPN router that is that I have set up and running in order to make sure to have this basically backup internet system running in a home network environment. And I've done a whole succession of playlist videos on this, just explaining basically what that involves. And basically it's, you know, having a second internet connection in your home or in your home office, whatever you're doing at home that you want to have really good internet for. And basically creating a system that both of these internet connections are going to be running into this piece of hardware, the load balancer. Now the TP-Link ER605 is categorized mostly as a VPN router, but load balancing. And the feature I'm using it for is just called failover. Now it doesn't have to be a VPN router to do failover. This feature will be in, you know, a lot of wired routers, SMB routers, typically a business router. In other words, not your average consumer router. Your average consumer router is going to have one port. And, you know, if you're looking at multi-wan routers, so that would be a good starting point. If you're looking to do this, you're going to be getting products that will be able to take in more than one internet connection. And if it's multi-wan, there's a very high chance it's going to have failover as a feature just that the firmware will be able to do that for you. And the ER605 is no exception. It can do this out of the box very easily. So what I wanted to do in this vid was to just show you guys the settings to set that up before I do less to be any confusion. This is just a network diagram of how I have this set up on this network. The load balancer in this case is ER605. I have a cellular and ISP routers both running as bridges. That's important because you want to have one router running on your network to avoid nasty things like DHCP server conflicts. So what you want to do is either set up these guys, the ISP router, whatever your two connections are, whether it's fiber and DSL or DSL and satellite, whatever's upstream of the load balancer, you want to have that configured as a bridge, if possible. If you can't have it configured as a bridge in the back end, then set up some bridge like settings. And that's basically assigning a static IP lease that's going to be outside of the DHCP server range on the load balancer. That was a bit of a mouthful. So this load balancer is going to be doing the actual networking on your network. It's going to have a the DHCP server is going to have a LAN range. And you want these guys to be assigned static local IPs that are outside of that range, both WANs. Now the ER605 can handle either two or I can actually handle three WANs as well. So in this case, I'm using just two WANs. And then what I've done is as I said, these guys are just running as bridges effectively my ISP DSL router and cellular. And basically everything on the LAN side, this is networking for my whole house. We're talking about NAS media center, desktop computers, wireless access points, the whole shebang, everything's coming out of the LAN side of the load balancer. So first things first would be to retrace my steps when I set this up network one and you're going to want to out of the box, it's going to have only the first one port, only one one port and four LAN ports. There's five, five ports on this device. And they are gigabit ports. So it'll support up to 1000 megabits per second in terms of throughput. So that's great because, you know, some of the older TP-Link load balancing routers, business SMB routers, like the TR470 only do 10 100. So if you have a faster internet connection, you don't want to run it through a 10 100 port because you're going to create a bottleneck. So if you're using two, and you can also you could also do a triple one setup, which would have, you know, two backup connections. But I think most people doing a failover setup for just this purpose of high availability. In other words, no interruptions to internet. If the ISP is down, let's bring up a cellular line. Most people would probably home users would be happy with just two one ports. If you're looking to do something more complicated, you're probably using more sophisticated networking gear than TP-Link. So the two ones are probably good for most people. So you need to tick one LAN one, that's the interchangeable. So you've got three of these ports. Sorry, technically speaking, two interchangeable ports. This is fixed as one, these two are fixed as LAN. And these two can be flipped between one and LAN. So out of the box, it's only one one. Therefore you want to tick this guy to get the second port into one mode. Leave the other three as LAN ports. And then it'll do a reboot. And once it's rebooted, you'll be into this config and you'll have two tabs, one in one LAN one. And this is ISP router for me. And something kind of cool is you can assign different DNS servers for each one. So you can have your when you're connected through the ISP, putting it through open DNS. And when you're connected through the backup connection, let's do Google DNS servers, whatever you want to do. Or you can actually have a you can have DNS servers for everything. And that's another option. But that's just I've just done it like this a bit duplicitously. I've entered it for both one, even though they're the same servers. So this is the configuration that I've gone for. I've set the MTU to maximum. No upstream or downstream bandwidth constraints. That's for metering. You don't need that. And you don't need need need to change most of these things. The default gateway is going to inherit. So you're going to have that gateway login for the routers. And that's going to remain I've assigned it to be static. So that hopefully should not change. And it's connected to that one. And status is connected. So that's the kind of important thing is you want to make sure both of these, if they're supposed to be up, they have connectivity, they should say they are connected. And if they don't hit connect and see what happens. And you can also manually disconnect them as well. So this is the cellular router. This is I mean, these are both one and one LAN one. These are actually both physical routers sitting in my networking cabinet. They're doing virtualized anything their real pieces of gear. And likewise, it's inherited a different gateway for this router. Dynamic IP is it's working for me. The only time I did have a bit of trouble was this at the start. And that was when I saw that was basically when it was flipping over to the cellular occasionally, when the primary seemed to be working. And I fixed that by basically just checking upgrading the firmware, that was the fix. And now it's fine. I'll show you just at the end of this video how to periodically spot check. But I'm trying to just get all the information covered here as quickly and efficiently as possible. So you want to connect your routers. As I said, you want to have the IP addresses of those one routers outside of the LAN range, which can be found in LAN. And once that once those are connected, and they the routers upstream of it have internet connectivity and their showing is connected, then you've got two connections to use. And now all that needs to be done is for you to set up the backup rule. And that is in transmission and load balancing. Now, according to the user manual, you are supposed to have load balancing enabled, even if all you're doing is failover. So click on enable load balancing. And then you're going to have a link backup. And this is where you configure the all important backup rule, right up to think about the situation up to now, the load balancer has two viable internet connections coming into two different one ports, it's got one and it's got two. And you've got all your stuff networked into it. But if all you want to use the other connection for is backup, you're going to need to spell that out, so that the hardware knows only to use that as a backup. Otherwise, you can do other cool things, such as application optimized routing and create the lands and other stuff. All I'm doing with my TP link ER 605 is failover. That's the only purpose it has on my network. I'm not utilizing the VPN. I'm not utilizing a lot of 99% of the features, just this, but you still need to click on enable load balancing. And then you need to set the backup rule. And my backup rule is pretty simple. The primary one, I'm telling it, well, that's one. And the backup is going to be the first interchangeable ports. And if I wanted to be the other way around, I would just assign the ports differently. And that is all it is. That's basically we're done now. That's the backup in place. If you have three ones connected, then there's going to be a difference between these two failover settings because let's say, I don't know, you have a, you have a fiber connection and you've got a 4G and a 5G line for some weird reason, you want to have, you know, two backup cellular networks. So you've got three going in. And this would be if either primary failed, let's say, sorry, that was a bad example. Let's say two fiber lines, two different companies and cellular backing those up. So this would be, well, if either of the fiber lines gives it out, we're going to bring up the backup. And this is going to be different. This is going to we're going to need all of those primary ones to fail, in which case we'd be ticking on two ones from this drop down, but we've only got two. So in this case, it's simple. The primary is one backup is one LAN one, and I've gone for failover. I clicked enable. And the final thing to say in this commentary is that the online detection, you've got a few options here. The automatic mode, according to the user manual, I believe, don't quote me on this, is that it's going to ping the DNS servers you've assigned to us or your ISPs ones. And that's going to be how it's going to pull for online connectivity. You can also assign it, you can also give it manual servers. So here's Google DNS servers, or final option, you can have it set to always online. And therefore, you know, as the name suggests, the firmware is going to assume, well, that's always a viable connection. And we'll just assume that's live in all situations. That's really all there is to say about it. That is it set up. And one other final thing, how are you going to make sure it's working? Well, this is one way to do it. There's stats traffic statistics. Now, how do I know this is working fine? And my difficulties with it turning onto the wrong connection have been overcome by that firmware upgrade. Well, look at the traffic stats. So this is the ISP. This is what's supposed to be primary. One LAN one is supposed to be cellular. And look at this column here, total RX bytes. Now, this is since it was last restarted. So it's pulled in 2.9 gigabytes of internet from the ISP connection. And by contrast, it's only pulled in 104 megabytes from the backup connection. Therefore, whatever that ratio is going to be, one to 30 approximately, that makes absolute sense that actually that's better than saying 2.9 and zero, because then you'd say, well, is it actually working or do I just know downtime on the primary? This tells me that there is a small bit of downtime, and the cellular is doing a little bit of work, not a lot of work given that I'm paying for a 20 gigabyte cellular plan. But whatever, it's better. It is there. And it brings me a lot of comfort to know it's there and that if there's any roadworks, this is when it tends to go down. That's when the ISP line has a habit of going down. Then this guy is going to flip me over to cellular and cellular is going to pick up the slack and going to keep connecting. And it's supposed to flip back. I wouldn't always count on it. If you ever have unusually slow connectivity, just check. Go on to who's my ISP and you'll see what connection you're using. And there's any problems you can resolve those, maybe by a reboot or something. But I believe it should flip back, but I'm not 100% certain about that. But in my case, I can see it looks like everything is working fine. Thankfully, finally, because as I said, that was there was an old firmware that had a bit of buggyness that would flip on to cellular for no reason when primary was fine. But 2.9 to 104 to me looks just about right. So that's my video, guys. Failover configuration on the ER605 TP-Link automatic gigabit multi-wan VPN router for provisioning high availability internet in a home networking environment, or has to be said, this would totally be viable for business as well, and maybe even more applicable in that kind of environment.
