Your default gateway is on a different network to your machine. The PC will be trying to send all external data to 10.25.16.1 but it won't know how to send the data there as your pc only knows how to send data to machines in the 10.25.20.x range
You either need to change the subnet mask... (I think it should be 255.255.251.0 but check my maths) or change the ip address of your pc.
You may find this helpfull
