Hello, I am behind a FortiGate 60E(v6.0.4 build0231 (GA)) and I have some remote sites with DynDNS so I can make VPN connection. What I am just realized is that if I ping my xxxxx.dyndns.org it always return the 208.91.112.55, but the real ip is another! If I go to another pc which is not behind the Fortigate with the ping I am getting the real ip.

Thanks!

The propagation time of updating DNS records varies from DNS servers to DNS servers - it could takes seconds (minutes) to a few days or more. Another possibility is the computer, fgt or other device (up stream) may be caching stale DNS info.

What DNS servers (IPs) is the fgt using and is it the same DNS server info passed on to the clients behind the fgt?

This xxx.dyndns.org name I have it over a year now, the fortigate I have a month that I had installed! In both machines I use google dns.
