Static DHCP (aka DHCP reservation) is a useful feature which makes the DHCP server on your router always assign the same IP address to a specific computer on your LAN.
We did this with a DDWRT and the Asus RT-N16 Router in the Class that we use for this Project.
As you can see we recerve 2 IP’s so that belong to the Weberver and the Mailserver.
We allso made a test to se if we cod catch the Mailserver for a client
