So I changed IP of the object, and object was used in all NA, ACL statements, etc. It actually started working but took like 20 minutes or so for some reason. Yes re-registered. Do you have any idea why that may have been the case?</P> Thu, 06 Apr 2023 11:58:00 GMT CiscoBrownBelt 2023-04-06T11:58:00Z https://community.cisco.com/t5/network-security/changing-ip-of-remote-device-connected-to-fmc/m-p/4808940#M1099272 <P>Basically if you change the object IP (device IP changed, and worked or was managed fine in FMC) for a remote FTDv device managed in the FMC and it will no longer properly connect or register, confirmed there is 2-way traffic (up to applciation data exchange), what else could be the problem or what else should I look at?</P> Wed, 05 Apr 2023 16:14:08 GMT https://community.cisco.com/t5/network-security/changing-ip-of-remote-device-connected-to-fmc/m-p/4808940#M1099272 CiscoBrownBelt 2023-04-05T16:14:08Z https://community.cisco.com/t5/network-security/changing-ip-of-remote-device-connected-to-fmc/m-p/4809156#M1099281 <P>If the ports are opened (as per the FTD and FMC communication) and NAT OK that should work.</P> <P>Note: if the FTD IP changes, you need to de-register and re-register. is the FTD behind NAT?</P> Thu, 06 Apr 2023 00:23:28 GMT https://community.cisco.com/t5/network-security/changing-ip-of-remote-device-connected-to-fmc/m-p/4809156#M1099281 balaji.bandi 2023-04-06T00:23:28Z https://community.cisco.com/t5/network-security/changing-ip-of-remote-device-connected-to-fmc/m-p/4809437#M1099300 <P>Hi, yes it is.
