DynDNS peer on FTD

[JACQUES DU PLESSIS]

Hi all,

We have a IPSec requirement to peer with a DynDNS FQDN on a FTD 4110 (6.4). Is this at all possible to do?

I see there is a Dynamic option where you specify the peer IP address, but I cannot find much information on it.

Hi @JACQUES DU PLESSIS 

 Never used but on this document it says that FQDN feature was introduced in FTP 6.3 and was not there in the previous version. It does not mention VPN but I believe if it is possible to use the FQDN object in order to start IPSEC, you need to be at least in version 6.3.

Thanks for the reply. I was more referring to this. It seems that you cannot enter anything other than an IP address in the field. There is the dynamic option, but I am not sure how if works:

that´s my point. You are running version 4 and as per the doc I share, FQDN is avaible in version 6. If you upgrade to version 6, you may see the option to select FQDN over there.
