Dear Sirs,
We have a Virgin media fibre broadband service at our residence which is experiencing connectivity issues through a particular backup device. Other services and devices seem to work fine. Further tests by our IT consultant reveal that connecting to a specific IP or DNS service seem to return errors, in particular while using DDNS services. When we take this same backup device to another location and try connecting through a different ISP the device connects without any errors. The problem seems to be establishing connection from our residential internet connection supplied by you. DNS name does not resolve and tests reveal DNS server errors.
We are currently using a Hub3.0 supplied you which is very restricted in it's ability to configure DDNS and other services including any firewall services.
Please advice on what the issue could be and where we could start troubleshooting.
Please also check and ensure that the IP address [Removed] is NOT black listed.
Regards
Mukesh Shah
