    hi,

     

    by default the LAN ports on desktop models are switch ports.

    They are represented as just one interface because all belong to the same broadcast domain / same subnet.

     

    If you want to use more ports you have to change the port mode from 'switch' to 'interface'. You can do so in the Network>Interface section. Beware that all configuration related to the 'internal' port need to be removed before you are allowed to switch the mode. Check these:

    - policies

    - address objects assigned to that interface

    - DHCP server

    - static routes

    I should add that on some but not all models the internal switch is called 'lan' in v5, and 'internal' in v4 of FortiOS. Some multi-multi-port models come with single interfaces by default. So check your config before beginning the procedure.

    Thank you ede_pfau!  I will try this procedure this weekend.

    Do you have any idea if changing this configuration, will make work the LAN ports as layer 3 switch? What I want, is to push a public IP thru LAN 5 and I don't want to install a layer 3 switch in between my ISP and my firewall.

    Thanks
