We have an T1 internet connection installed in our office. The T1 line is connected to an 5-Port Switch so we can use the 5 difference fixed IP address. Is there anyway we can assigh each fixed IP to each individual ports ? For example, port 1 will be 18.104.22.168, and port 2 will be 22.214.171.124 something like that. We only want each port can only get 1 fixed IP even we connect another switch on Port 1. We want each port can only has 1 IP address no matter what kinds of devices/computers connect to it and the IP cannot be changed. Is that possible ? and what kind of devices I should use ? I must use the 5 public fixed IP address and cannot use NAT or any internal address.
