2. Assign a port to a LAN by selecting the checkbox next to the port number. If a port is assigned to another LAN, it must be unassigned prior.

3. Gateway IP: Enter a gateway IP address.

4. Subnet Mask: Enter a subnet mask.

5. DHCP: Select the Enable DHCP checkbox to enable and configure DHCP:

  • Enter IP addresses for a DHCP pool start and end. A DHCP pool requires a start IP address when configuring both a DHCP pool end & a DHCP lease time.
  • Enter a DHCP lease time. A DHCP lease time minimum is 5 minutes, maximum is 10080 minutes (7 days).

6. Advanced DHCP Options: Select the Advanced DHCP Options checkbox to enable and configure the following options:

  • Option 6 (DNS Server): Enter a DNS server IP address. 
  • Option 33 (Static Route): Enter a destination and gateway IP address.
  • Option 42 (Time Server): Enter a time server IP address.
  • Option 66 (TFTP Server): Enter a TFTP server IP address, or a URL up to 250 characters.
Configured option values are sent to DHCP clients when they renew their DHCP lease.

DHCP Reservations

DHCP Reservations allow you to reserve IP addresses in a DHCP pool for specific devices. This ensures that only that device will have that IP address, and will not be assigned to another. To add a DHCP reservation, follow the steps below:
