If you are deploying an FMC device in a lab or in production, the default IP is 192.168.45.45\/24. If this IP doesn’t work in your schema, or you don’t feel like building out a host on that network to configure it via the GUI; you can change it’s address relatively easily. Use the following commands to change the IP Address and set a Default Gateway. Let’s take a look.<\/p>\n\n\n\n

Typically, on a fresh deployment, you can use the following credentials to login:
Username: admin
Password: Admin123
Password for Version 5.4 and prior: Sourcefire<\/code>

To set the device’s Default Gateway use this command:
sudo ifconfig eth0 x.x.x.x\/yy<\/code>

To set the device’s Default Gateway use this command:
sudo ip route add default via z.z.z.z<\/code><\/p>\n\n\n\n
