UTM home cannot access specific sites

vasileiosg

Hello,

 

I have a strange occurrence. I have activated Intrusion Prevention and I had also the Web protection which for now I have turned off. I have forced every device in my house to go through the UTM9. 

Even though everything is a bit slower, it is acceptably ok to browse the internet. However, two specific websites are next to impossible to open: youtube.com and bbc.co.uk.

 

I have no idea why nor I know where I can check it!

 

Any ideas would be appreciated!

    Please allow me to correct this. ALL HTTPS pages are a problem. Either not loading them, or I have to reload them a couple of times before they work, or they don't work.

     

    Here is my dashboard at this moment:

     

    Firewall is active with 8 rules
    Intrusion Prevention is inactive

    Web Filtering is inactive
    Network Visibility is inactive
    SMTP Proxy is inactive
    POP3 Proxy is inactive

    RED is inactive
    Wireless Protection is inactive
    Endpoint Protection is inactive

    Site-to-Site VPN is inactive
    Remote Access is active

    Web Application Firewall is active

    Sophos UTM Manager is not configured
    Sophos Mobile Control is inactive

    HA/Cluster is inactive
    Antivirus is inactive
    Antispam is inactive
    Antispyware is inactive

    Since Web Filtering is disabled, your problem has to be in Firewall Rules, DNS, or speed-duplex mismatch on a NIC.   To avoid speed-duplex problems, ensure that all devices are set to Auto-Auto.

    That helped but it is still a bit slow.

     

    I wonder though why using the Web Protection is "normal" to be very slow? In implementation that i have done to different companies using hardware UTM it wasn't slow.

     

    I am asking because i do want to use the Web Protection.

    Vasileios, does doing #1 in Rulz give any information?  If not, then how does your configuration compare to DNS best practice?

    Cheers - Bob
