We need to setup an FMC on a different subnet than the FTD management interface so I will configure the gateway on this interface to reach the FMC. At the same time, the management interface will be connected to the same network than the production traffic, so it will have an IP on the same range than the internal firewall interface and also a the same static route towards the internal router like the management interface. Is this supported by FTD? Does the management interface reside on a different VRF?

Thanks for your reply. So I could even have a default route on the management interface of the FP2100 that matches the same default route on the LAN FTD interface, right?
In some document I've read, they suggest to configure the management default GW as the IP of the FTD LAN interface which is kind of strange specially during the initial setup where you need that route to reach the FMC, before configuring the rest of the interfaces.
