Configuring the FortiGate interfaces
This section configures the interfaces that connect to the companies’ internal networks, and to the companies’ ISPs.
All interfaces on the FortiGate unit will be configured with an IP address ending in “.2” such as 10.11.101.2. This will simplify network administration both for the companies, and for the FortiGate unit global administrator. Also the internal addresses for each company differ in the second octet of their IP address - Company A is 10.11.*, and Company B is 10.12.*.
This section includes the following topics:
| If you cannot change the VDOM of an network interface it is because something is referring to that interface that needs to be deleted. Once all the references are deleted the interface will be available to switch to a different VDOM. For example a common reference to the external interface is the default static route entry. See “Configuring interfaces in a NAT/Route VDOM”. |
