Robinson,
You have to check if the gateway machine/router can ping the different network. If that fails then you need to ask the networking team to fix it .
You should have a proper network default gateway to route your packets to different network. Ping could fail if you don’t have a Gateway ip configured or the gateway doesn’t know how to reach the different network. If your gateway is a router then you need to have a static route in case they are not directly connected.
Once the problem is solved you should be able to reach the different network.
Thanks
Daniel
