getting DDNS working with DYN.COM service

I have to deploy some PAN firewalls at locations where ISPs only support DHCP. This seems to be increasing in some countries. I subscribed to DYN.COM but I am stuck on the certificate profile. I need the DYN.COM public cert and CA for domain, but am not successful in getting it. I have a support case open with DYN, but taking a long time to get a response. I may have to change services. 
I am hoping someone in the community has paved the way on this and can provide a successful solution.

@namijo ,


I hope is using the same certificate for their URL browsing and dynamic DNS serv ice, if yes, you can browse their URL and take certificates from there. In not, i would prefer to take a packet capture from the firewall and identify the certificate used in Dyn DNS service.
