While this article is interesting from a tech perspective one should note that doing actions like this will most likely go against service agreement with your provider as it is technically stealing cable 🙂
Yep – if you want to make sure you’re in compliance with your ISP’s service agreement, check to see whether this is permitted. In most cases it probably isn’t.
But it’s also likely that your ISP will never find out, and from their perspective it’s impossible to tell the difference between a NAT device connecting multiple computers in your house and a NAT device connecting multiple computers in your house and your neighbor’s. 🙂
I’d be more interested in a scenario where both parties have their own isp and just want to use the other isp as a fallback.
So A uses connection A and B uses B. But when connection A fails A is using B and vice versa. I haven’t figured out how to tackle that yet. At least not with one wire between the to networks. Oh, and both networks have to be sepperated.
Could this be done with V-Lans?
Olaf: I was actually thinking about writing a howto exactly like that. 🙂 I might put it in the book, might put it elsewhere. You could setup a point to point link between the houses, via wireless or other method, and use the other’s Internet as a backup (or load balancing or whatever you wanted).
Just this week, we completed a dual WAN pfSense router at our church. One WAN is primarily for VOIP and the other for Internet access. All it took was two pools and assigning the PF rules to prefer one pool or the other. Our configuration is large with eight VLANs behind the router and another router doing NAT for one of the WAN interfaces.
