Network guru needed

[Trooper]

I have set my show up on 192.168.2.0 subnet, so it's just the show controllers an Pi's.  The home network is 192.168.1.0.  I have my router for the show connected to the home network by the wan port.  I can see the 1.0 network and Internet from the 2.0 side,  I cannot see the 2.0 from the 1.0 side.   I have a route set up on the 1.0 router that sends traffic to 192.168.2.0. Through the the wan ip of 192.168.1.130.  I think I am missing something on the 2.0 router.  Can you help me out?  Every time I try to put a route in it tell me I have an incorrect gateway.
It has to be something simple,  but alas not simple enough

Thanks
Andy

make your subnet mask 255.255.254.0 for all your devices. Then you can access 192.168.1.0 thru 192.168.2.254

Even if you could get routing to work, the problem is that some (most?) controllers don't allow you to specify a default gateway.

e.g. in a E682, though it has a subnet mask (for who knows what reason), you can't tell it where to send traffic that doesn't belong in that subnet.

So you're basically stuck having to be in the same subnet as the controllers anyway.

wftxlites's mechanism achieves that. So does just renaming all of your 192.168.2.x devices to 192.168.1.x.


I'm not sure if you're trying to do isolation here to reduce traffic overlap - but you don't need subnets for that. Just putting your show on a separate Ethernet switch from your main network will achieve that.

Generally, if you have routes on both routers pointing at each other then the traffic will go in both directions. I have  made a similar setup before, but the router were connected wan to wan ports. In your case I realize that is not possible because one of you wan ports is the internet. I originally thought that both subnets were on the lan side of a single router. Therefore, I suggested the subnet mask change on your devices. Which would allow all ip's to communicate with each other.

The router wants the gateway to be in the same subnet, so that is why it is complaining.

I know that is of no help. I will think about this a bit and maybe there is an easy solution....

Maybe you could provide the routing table of both routers.
