I suspect that they are miss-understanding what you are trying to do.
The error that you mention, where are you seeing it?

Also, the NETMASK should be 255.255.255.255 and not 255.255.255.248,
regardless of what the real subnet is. You also need to have
another address attached to the 174.121.60.x/y network, probably on eth0.
