Hi

Looking for some advice , or thoughts of the pros and cons of this setup

I am looking at putting a 2nd vdsl to be run as a dual wan setup.
We have a large household and at peak times when we all want the net, I need more throughput.

Streaming/Gaming/Voip & regular downloads are the primary use of the connection.

I have 1 vdsl connection setup as a pppoe wan on a Rb1100ah2 this is fed from a repeated 3km Ubiquiti AF5x link

Has anybody here in Nz had any luck with any Isp getting 2 residential connections bonded. (long shot I know)
I am with Snap , I read somewhere they had team members in there Noc playing with this. ( Both lines will be with Snap )
Just reading the thread were Layer 2 bonding has been offered in the past as an extra from the isp , what is required to setup this on the mikrotik.
If one modem dropped does the other carry on ?
Can anybody comment on the expected cost of this.

If bonding is not a go the loadsharing/agregation will be done locally what issues will this present with gaming / voip. Or any other traffic or protocol issues this will throw up,

How will it affect port forwarding for a couple of rules I need, Will this be easy to setup ?
Will I have to use Google dns , servers

What config would I need to setup gateways that would allow assigning groups of devices on Lan to each router and then a master gateway that would use both.

I remember seeing a thread from JamesL ? , he had setup with Dual wan with pfsense with 2 x vdsl showing a speedtest of 20/60
How is this still working for you.

Thanks

Jeremy

I ended up disabling it as it was more hassle for me.

The main issue was with some CDN's, because the connections were with two different ISP's some pages would break due to the subsequent DNS request returning a different IP to what was expected. If the connections are with the same ISP then it probably wont be an issue.

You can use firewall rules to specify certain ports to only go out one interface for the likes of voip, same with port forwarding you just select which gateway you allow traffic to come through

I think it would be easier to have two lines, and specify the default gateway of one set of PC's to one and the rest to the other. Crude but works.

On the Mikrotik it just becomes really difficult to manage. The simplest way is equally weighted default routes but then that breaks HTTPS, CDN's etc etc because it just round-robin's between the two WAN's. So to stop that happening you have to do packet marking (which is just nightmare to manage) to make sure a connection continues to use the same WAN but then that sort of defeats the purpose of 'load balancing'. It would help with many many users but not so much for just a handful of people wanting more speed.
Then again, I'm no guru on RouterOS - maybe there is a better way. The best option is definitely a bonded DSL connection but I've never heard of anyone doing it successfully. Perhaps try companies like Solarix (ex-Unleash), DTS, Voyager etc who deal solely with businesses. HSNS can be delivered over a bonded DSL circuit but won't do the speeds you are looking for (10/10 is the highest you can do on DSL I think) and it will cost around heaps!

WorldNet did some stuff like that a long time ago, but not bonded since wasn't supported by Telecom at the time. You might be better off just configuring the router to spread the load on a per-user basis.

Time to find a new industry!

Have you looked into MLPPP - this is supported in Mikrotik RouterOS.

I'm not sure if Snap support multilink.

Where in NZ are you located?

How big is your household?

If you are getting congestion within the house, you must all be seriously saturating bot directions of your connection. Have you ruled out your internal network causing the issues?

Have you considered some sort of QoS or shaping appliance within the home? Smoothwall or similar? To saturate a VDSL connection, you must be hammering it (we have a 50/10 HSNS connection at work, and 50 people use it with never an issue. I so some big downloads at work, as do others and we are on a managed WAN to Australia and never have slowdowns with our internet connections).

He's got a Mikrotik RB1100 which can do excellent QoS. A little bit of knowledge how to mark packets and connections in /ip firewall mangle and a couple of simple queues is all that's required.

Snap don't support MLPPP. Most of the ISPs I asked said it's too much of a hassle.

I've got two Snap VDSL connections which I'm load balancing with an EdgeRouter Lite.
I'm just doing the nasty 50% of packets out each connection. Most sites handle the rapidly changing IP fine, and I'm manually adding exceptions for ones that don't.
It's a hassle but the speed improvements are worth it!

I have done this before, back in the day when I had ADSL and a Woosh connection (wireless) - the DSL modem was x.x.x.1 and the Woosh for x.x.x.2. Then I just set the default gateway on various devices to one or the other. Worked perfectly fine.

Advantage is that you can push specific users/devices through a specific connection, so if you had ADSL and VDSL you could force downloaders onto the ADSL and keep the VDSL for other things (gaming, etc).

Hi,

Am rural in Alexandra,

I also work from home, my work is not in an I.T field , (I.T is a hobby)
I have 40+ connections on my network.
I have asked Ralph & snap/degrees about MLPPP, Have had no response.
THink I will need to look at the other ISP's if I look go this route. One looked possible with a $50 hire of there managed cisco router.
I am after the holy grail of raw bandwidth and low latency.
My interim thoughts are 2 x vdsl with 3 gateways (vdsl1,vdsl2, Mikrotik bonded) to get by on. Till I can sort a MLPPP
I would use upwork to hire a contractor to add the functionality to the Mikrotik I need.

Cheers
