At least it isn’t like my setup is complex. The home net uses 10.10.10.x because it’s easy to remember, and I have a couple dozen fixed IPs assigned via DNS. If I use two routers I’ll probably have one be 10.10.10.x and the other 10.10.1.x or something. My IP routing knowledge is awfully rusty, though, so hopefully it’ll be easy to make sure the two subnets can talk to each other.
