I have a two part question related to subnetting.

First part:

I need help in picking subnets. I need to pick four subnets with an approximate number of hosts in each one: 30, 220,160, 275.  Each subnet will go in its own vlan.

Our default equipment comes with a 10.45.X.X IP and 255.255.0.0 subnet.  Our current customer has stated this will not work since it is not defined enough.

I need to narrow down the subnet but I would still like to use a 10.45.X.X scheme if possible.  I am not very great with the design part so any help would be appreciated.




Second part:

Our network is going to be joining the customers network through their firewall.  Their firewall will be doing the routing and vlan administration. We will also use part of the customers network for connecting a few workstations in their offices.


As mentioned above, the hardware comes default with a 255.255.0.0 subnet. For maintenance purposes, it would be best to leave it on the default and not switch the subnet.

Customer thinks it is possible to leave our equipment on the 255.255.0.0 subnet but connect to their firewall using a subnet like 255.255.255.0.  Does this make sense?  Does it make sense if the equipment also needs to use part of their network to connect the office workstations?
