Its possible to have 2 mgmt interfaces in FTD 1120

[GabrielGarciaF]

I am going to implement an FTD 1120 but the client does not want a condition greater than 30 min, just registering the FTD to the CDO takes 20 min, the option he gave us is to use a SOHO router but those routers give IP through DHCP, I have already managed to integrate the FTD to the CDP through DHCP but when I remove the DHCP and connect the ISP to the Eth1/1 port the FTD stays in limbo, since the ISP's IP is static, I try to change the IP in the CDO (outisde interface) from DHCP to static but the device is also lost, I restart it but the same problem continues, the device is in standalone and when I want to enable a second interface it gives me a warning that it is not possible

Or how i can disable mgmt interface configured by DHCP and enable Eth1/1 to use like mgmt, im is tried to do it but appear the next warning

Hi MHM

I used the next link to change the mgmt interface to data interface mgmt and was success the change

https://docs.manage.security.cisco.com/cdfmc/index.html#!t_change-the-fmc-access-interface-from-management-to-data.html

Whit this changes i can minimize the impact in the network operation client and im is doing its in a lab i hope it be the seam in the production device

But we don't change IP we only change way FTD get IP

And different between two way is missing of default route when we set static IP.

Ask ISP what IP You can use and IP of GW
