ATP200 Content Filter

Marko75 · April 2020

Good morning,
for a few days we have been unable to access the public url of the NAS https://cloud.la-med.it although this is inserted in the trusted sites of the ATP200 device that protects it, only from the LAN this url cannot be reached even by deactivating the Content Filter.

Another strange thing is that from an ATP100 in another location this url is not in the whitelist but I display it correctly ...

As your description, it could hit the issue of triangle route.
On the NAT rule related with NAS, can I know do you enable NAT lookback?

Can I confirm the scenario that the NAS get public IP, and PC which is under ATP's Lan cannot access NAS with URL?
If so, can you ping or access to NAS with IP address?
