If you are running ComOS 3.5, you have VLSM. You are good to go.
What your provider seems to want to do is to give you one address for your
port and one for his end. This is using the traditional don't use
first or last address, so a 255.255.255.252 is a two machine subnet, yours
and his. His router understands subnets, so does yours. Just set your
wan ports address and netmask and everything should work out just fine.
