I have L2 cisco swtiches which are connected to my LAN.Since I am about to exhaust the IP addresses assigned to our organization, I wish to know how can I best use my present H/w to accommodate more users since my organization is reluctant to sanction additional fund for IT infrastructure.
I also have 2 UTM device which I am using as firewall. It can be used as DHCP and most probably as L3 switches(not sure) also.
Please advise.
