Thanks to member olnyodin I was able to get my network up and running. I have a question about routing to additional subnets.
I can now go from my .20 network to their .40 network working through the switch. I now need to connect to a server on their .10 subnet. Now their .40 subnet and .10 subnet can see each other. I was thinking that since i can get to the .40 network any requests for the .10 network would be forwarded accordingly. They are not.
If i plug a PC into the connection that I have on their .40 network and give it a valid .40 ip address, subnet mask and gateway I can ping the .10 network.
Do i need to create another Vlan on the switch, assign a .10 network address to it (say .10.50) and then make a route on my router that says
network subnet mask gateway
192.168.10.0 255.255.255.0 192.168.10.50
and then on their .10 main router make another route that has the 10.50 as a return path from their network?
basically repeating the steps that i tool to get connected to their .40 network?
