So I can find a lot of information about failover, that's easy. But they all depend on us sharing the same network or making multiple connections to each others ISP. We have different ISP's, and both work from home. I'd like to be able to set up a single wireless connection that can server as an internet failover either direction. The "either direction" is what I'm struggling with. Setting up a single direction failover is simple enough.
I'm not so worried about the security implications. We can both set up VLAN's on our wireless routers. Or even add a dedicated wireless link if necessary. We are running different subnets. He's just running stock but I have no problem upgrading that if it's something I can do without Cisco grade hardware. I'm currently running DD-WRT. I've looked at Ubiquiti stuff, and it has great failover options if I have both ISP's at one location, but the only way I can figure out how to do what I want with that is to use 2 of them, and set up 2 separate wifi bridges so each routers secondary WAN port can be on the others LAN. I'd rather do it with a single link, because our range is already pushing it, but good enough for a failover, especially with an external AP on one side.
If this can scale out I'd offer it to other neighbors too. We have 3 different ISP options but none are great. There's just 12 houses in a little cluster out in a rural area. It would be awesome to be able to build a mesh between the houses for auto fail over and maybe even better burst speeds.
Thanks!
Edit: Adding current plan: This is the best I can come up with right now. This requires two parallel wifi connections, with us each hosting an AP and a Client.
Like, it seems like I should be able to do this: Router between and configure the primary routers to fail over to a secondary gateway inside the network, which happens to be a router that knows of the other gateway on the other network? If I can do this, I can abstract away the wires with wifi, but I'm not sure what kind of hardware is even capable of doing this.
I totally accept that my hardware is not readily available to do this, so I'd take recommendations there as well.
