Hi,

Yes it is possible to have multiple interfaces configured, however, eth0 must be enabled and used for the initial provisioning of the VM.

I would suggest you speak with Support for instructions and ensure you have a good recent backup. But these steps should work.

- Add a new virtual interface in the hypervisor. The steps below are for VMware vSphere, use steps appropriate to the hypervisor version

[ul]

In the vSphere Client right‐click the Virtual Appliance and click Edit Settings.

Under Hardware select Add

Select Ethernet Adapter then click Next

Define the Network that the Adapter will be a part of then click Next, then Finish.[/ul]

- Connect to the FortiSIEM virtual appliance via SSH

- The network interface will not appear in the CLI as the interface hasn’t been configured. Configure the interface as follows

[ul]

Enter the following commands to copy the existing network interface config to a second file and open it for editing[/ul]

cd /etc/sysconfig/network‐scripts

cp ifcfg‐eth0 ifcfg‐eth1

vi ifcfg‐eth1 This will open the new config file in the vi editor

[ul]

Modify the new file with settings for the new interface as shown below[/ul]

DEVICE=eth1 Update this to ‘eth1’ as shown

BOOTPROTO=none

ONBOOT=yes

TYPE=Ethernet

IPADDR=172.16.20.210 IP address of new Interface

NETMASK=255.255.255.0 Subnet mask of new interface

[strike]GATEWAY=172.16.20.1[/strike] Delete, eth0 has the default gateway

BROADCAST=172.16.20.255 Broadcast address for the new subnet

[ul]

Save the updated file and exit by pressing the [Esc] key and entering the ‘:wq’ vi command sequence

Restart the network service with the following command service network restart[/ul]
