"Non routable IP ranges" is covered at https://en.wikipedia.org/wiki/Private_network
This is why you can't fix this with routing tables. I have run into folk that can't believe this and you give them time to ponder.
If you want to join the two networks to make a LAN, then you look into VPN solutions. But that's beyond the scope of what I'll discuss here. I may point to the VPN solution but setup must be done by the person that is going to care and support the system.
Again, the routers must support this so changes in hardware is not unusual.
Hi I've been trying to work this one out for a while with no success. This setup is in a 2-story house with 2 WAN connections each at opposite ends of the house.
Downstairs:
Router ActionTec T3200- IP 192.168.254.254 Subnet 255.255.???.0
DHCP: Required
Upstairs:
Router ActionTec T3200- IP 192.168.1.254 Subnet 255.255.???.0
DHCP: Required
Goal:
Allow a home automation hub to connect to devices on both networks.
These T3200 routers don't seem to allow static routes to be configured so is this setup impossible even with the addition of a more advanced router on the network. Replacing both T3200s which provide bonded dsl connections is not an option.
I was imagining that an advanced router with the automation hub on another subnet, 192.168.50.0 for example, might be possible but now I'm having doubts. Thanks for any advice!
