The DHCP server can hand out IP addresses as required for any VLAN, we have 35 VLANs here and only one DHCP server. Re: DHCP - Need to release IP addresses In the connected devices list there are 2 instances of the garage door, one with an IP of 192. Check “Enable DHCP server on LAN interface“. a DHCPDECLINE message to indicate to the server the address is in use. DHCP (Dynamic Host Configuration Protocol) is a network management protocol used to dynamically assign an Internet Protocol ( IP ) address to any device, or node , on a network so they can communicate using IP. In active mode, the link is automatically brought up during the network activation process. When using an external TFTP server such as IP Office Manager Set the “TFTP Server IP Address” to the IP Address of the PC running Manager but leave the HTTP address blank.
