Some public Network are not accessable

cirra

Hi Guys,

since some days i do have a very strange Problem. Some public Webseites like Facebook.com or even Sophos are not accessable through my UTM. Since the Access to those Webpages is possible while bypassing the Sophos it´s not an ISP Problem. Also i guess it´´s not a DNS Problem since the Sophos can resolve those hostnames successfully. ISP, Webfiltering and so is completly deactiveted.

Any Ideas whats going wrong here?

    You can test DNS by opening a command prompt and execute the following command:    NSLOOKUP www.facebook.com (or another site you would like to test).
    If you have deactivated web filtering, you may have "forgotten" to enable traffic on outgoing TCP port 443 (HTTPS). That would explain if all HTTP pages do load, but if HTTPS pages do not load.

    Can you post some lines from your firewall log where we might be able to see what is blocked?
