My Windows router is set up to use 192.168.16.1/24 as its IP address. I have just added a new IP address: 192.168.18.1/24. However, I am unable to ping this new IP address from my desktop. I have added 192.168.18.2/24 to my desktop, which is unable to access
I am also unable to ping 192.168.18.1 from within the server. I can ping 192.168.16.1 with no problems. I have also discovered that I am unable to ping 127.0.0.1 from this machine. This leads me to believe there is a firewall getting in the way. Can anyone suggest a way to debug this? I have tried completely disabling the Windows firewall, but this doesn't seem to have any effect.
As an aside, can you confirm that my use of the slash notation is correct? I believe that saying 192.168.16.1/24 is the same as saying 192.168.16.1 with a subnet mask of 255.255.255.0. What is the correct name for this notation?
Thank you for your time.
