In Preferences > IPGroup > IP Address Domain Name is not an option for entering the IP Address.

I need this because I use DDNS to resolve IP address of my remote routers.

For example, Domain Name is an option on this router when setting up IPSec VPN. I use DDNS domain names on my IPSec VPNs and it works fine.

Please allow Domain name for IP Address on the IP Address page.

Thanks Andy
