How to change the interface mgmt from public ip to private ip FTD?

ipv6x
Beginner
Beginner

Hello,

I have successfully register FTD to remote FMC.

1-FMC ---> FTD--->NATIP_FMC and PORT 8305 ----> REMOTE FTD-PUBLIC IP

Created ACL only access from FTD-Remote

Created VPN/S2S between both FTD.

Now my problem is how to convert the mgmt interface in private IP? without losing connection to remote FMC??

Hi ,
You can refer to this document the process :
https://www.cisco.com/c/en/us/td/docs/security/secure-firewall/management-center/management-center-mgmt-nw/fmc-ftd-mgmt-nw.html#id_46848

its similar to changing Ip address.

you can refer to this similar community post : https://community.cisco.com/t5/network-security/ftd-need-to-change-mgmt-ip/td-p/3673890 
1.Disable management of the device in FMC. Do that via Device Management > edit the Device > Device tab > move slider next to management section.

2. Change the address on the device directly using "configure network ..." command from the cli.

3. Edit the management address in FMC from the same place you disabled management. Then move the slider back to enable management. 

If its a production environment you can reach out to TAC to make sure you dont lose connectivity and be sure about that.
