ddns issue

Rudolph Wijburg

Hi,

I'm having a strange issue with DDNS on our XG firewall (firmware SFOS 17.5.0 GA).

Using the Sophos DDNS service everything seems to work as expected, the IP address is regularly updated without any failure.

However, when pinging "g****t.myfirewall.co", I get  "could not find host". Waiting more than 24 hours didn't solve the problem. The address is updated in the firewall, but unreachable.

Pinging the ip address works fine, also connecting through SSL VPN by using the ip address.

Any ideas ?

Rudolph

    Which DNS Server do you use? 

    The myfirewall.co DNS Record should be globally available. 

    Is the XG behind some NAT or something else?

    Hi,

    Thanks for your reply.

    Using DNS servers from Internet provider (Orange in France). And yes, XG is behind NAT (in provider's router's DMZ).

    But I don't see how DNS server could be the problem, since XG ddns updates regularly with the correct NATed public IP address.

    Pinging "x.myfirewall.co" doesn't work, whatever DNS server I use (not through mobile network, not through completely other Internet provider).

    Exactly the same setup has worked fine with another XG box (and a different x.myfirewall.co name).

    ?

    Can you perform some dig / nslookup ´s with different DNS Servers to check, if your DNS Record is already published? 

    Maybe there is some issue currently with this service.
