I have a "main" router that connects to the internet, and then a wireless router that connects to that. The main router's DHCP is disabled, and a computer hooked to that has a DHCP server running serving up 10.0... addresses with mask 255.0.0.0. The wireless router does not allow that subnet, but only 255.255.255.x choices.
I have four wireless client devices that connected to the wireless router. Two are somehow able to get 10.0... addresses from the DHCP server computer, in addition to the 192.168... addresses they get from the wireless router's built-in DHCP server. I can ping the 10.0... addresses from the DHCP server computer successfully.
However, the other two clients are somehow not able to get 10.0.... addresses from the DHCP server computer, but only the 192.168.... addresses from the wireless router's built-in DHCP. They can access the internet but not anything on the 10.0 network.
Why is there a difference among the clients, and how can I get the latter two clients to get 10.0.... addresses so I can reach them from the main network like I can with the other two?
