Point to Point Connection with multiple WAN

[ron15]

Ok. This might be a bit complicated but please I'd appreciate if you take time and understand what I wanted to do.

First there are two buildings in this setup...

Building A (BA) - My own house
Building B (BB) - A commercial building two blocks from my house around 500 meters. Dormitory

Wireless Point to Point: Might be two Ubiquiti Nanostation Loco M2.

BA Setup - Has own WAN with a small wireless/wired LAN. Home use only.

BB Setup - This might have multiple WAN 2 at least (Load balanced). It will have a Surveillance Setup with 5 or more IP Camera and a public WiFi that will cater big traffic like 60 devices.

What I want to happen:

I want to create a wireless point to point connection from BA to BB.

First reason is to save the WAN bandwidth in BB for expected 60 users by allowing access the surveillance via local connection. So accessing the camera from my house will not pass through the net instead it will act as local access.

Second, when traffic is not busy in BB i want tap to its internet bandwidth from my house to boost my home's internet(BA).

This is the restriction, from BA i want to be able to access everything connected to BB (eg. IP CAM, Internet, Servers, Shared Computers etc.). But from BB I want to limit the access to only my Server and Shared File, but definitely not my internet(BA). In short I could use BB's internet when I am in BA but I can't use BA's internet when I am in BB.

What setup would make it happen? Would this be possible? How can I make this work with the least expenses?

This is still on planning stage, I want to make sure that before I buy the equipments, the setup will work.

Thanks!!!

If you have a clear line of site I would use the NanoStation Loco M5 instead of the M2. The 2.4Ghz band is pretty crowded and has a good deal of interference.
What you want to do is not complicated from a Pro perspective but is pretty complicated from a consumer prospective. How versed are you with routers and networks? If you have a little bit of knowledge then I would purchase two Ubiquiti Edgerouter Lite's and put one at each office. They are $100 each and could do all the routing you need. If you are not very versed with this type thing you would probably be better off hiring someone to help you as you could make a real mess with your networks if your not careful.
Also what do you mean by this statement "Second, when traffic is not busy in BB i want tap to its internet bandwidth from my house to boost my home's internet(BA)". What do you mean by boost, as you cannot combine the two internet connections to gain greater speed (though you could do some type of load balancing possibly).

Thanks abailey!

Yes, m5 was my first option but I cant find any of it on local stores.

I'm really not sure if i consider myself well versed in networking or not. Maybe I'm the kinda "I'm willing to learn if I do not know it guy." so I do not quit easily. I know OSI levels, well hope that could give a hint on what i know? hahaha... Any way I got your point on finding some one else to do the job.

BTW i think I got it sorted out except on the part where you quoted

"Second, when traffic is not busy in BB i want tap to its internet bandwidth from my house to boost my home's internet(BA)".

Have bad experience connecting with different subnet (phobia)...

This part, I am really thinking about load balancing. When boosting I mean increasing my bandwith with p2p, torrents and multiple user access. I'm aware that some programs will just choose one WAN to send and receive data.

The part that kinda confuse me here is I am interconnecting two LAN with WAN in each side. And want to load balance the internet of both from one of the LAN.

Without something really complex, the router on BA side is going to treat its WAN connection to the internet and the WAN connection to BB over the wireless bridge as two regular old WAN connections no different than a cable and fiber connection, or two DSL connections or whatever connected up to the router.

You can set weighting (most likely), round robin or other rules on the router for the load balancing. There is going to be no way to do enable this for when "BB isn't that busy". There is no way for the router to determine how busy the actual internet gateway router on the BB side is or not. It MIGHT be possible that you can find a load balance router that can set rules weighting the connections based on time of day if you know what patterns there are with the BB internet connection (IE very busy during the day, but not busy evenings and nights or something).

For BB to BA, you just have to setup port forwarding on the BA router to redirect the appropriate requests just to your server or other resources. Nothing on BB is going to be able or look to BA to get out to the internet (unless you do work to explicitly enable this, which would be some significant work).

It is all going to be up to the router on how load balancing goes, the client applications aren't going to have any say in the matter (as they don't do routing). So it won't be that some programs will only use the one connection. The router determines what gets what path (though you may be limited in how well balanced you can actually make things. Router isn't going to know that netflix is going to be requesting 10Mbps of data and your POP email request is going to be requesting 2Mbps and your COD4 is going to be requesting 1.5Mbps and your driver package download is going to be requesting at 40Mbps or what not and properly balance, it is going to be a lot more "round robin". Request 1 takes path 1, request 2 takes path 2, request 3 takes path 1 and so on. Again, you can do weighting and there are some more intelligent options than that, but unless all connections are of a similar type, load balancing is unlikely to be truely all that even (which in a lot of ways, is why load balancing should really only be done when two connections are of fairly even performance, that or you setup rules so that certain applications or clients will only go through one connection. IE setting an AppleTV to only go through the DSL connection, and everything else to hit the cable connection, or setting up all torrents to go through DSL and everything else cable, or what have you).
