Configure the VLAN interfaces on FortiVoice and FortiGate

1. On FortiVoice, go to System > Network > Network and click New.
2. Enter an Interface name.
3. Set Type to VLAN.
4. Set Interface to port1.
5. Set a VLAN ID of 100.
6. Under Addressing Mode, enter an IP/Netmask of 192.168.100.99/24, and click Create.



7. Create another entry for the data VLAN on the same interface, this time setting the VLAN ID to 200 and an IP/Netmask of 192.168.200.99/24.
8. On FortiGate, go to Network > Interfaces and click Create New > Interface.
9. On the internal port, configure VLAN interfaces for both voice and data VLANs, but set their IP/netmasks to 192.168.100.1/24 and 192.168.200.1/24 respectively.



10. In the configuration of the new VLAN interface, enable DHCP Server so both VLAN interfaces have an IP Address Range.



11. Go to Policy & Objects > Firewall Policy and create an outbound policy for the data VLAN so the PC connected to FortiFone can access the internet.



12. To allow FortiFone to auto provision with FortiVoice, create another policy between the voice and data VLANs.
