Filtering

I installed Sophos UTM OS today for the first time. I'm new to networking etc so I'm not sure how all this stuff works. I blocked a few sites but they are not being blocked. Is there some client config I need? I think I skipped a few network settings during first time setup. Please help
Thanks

  • Hi Nicholas,

    Check the following settings and post screenshots for the same.

    Configure the Internal Network host in Allowed Network for DNS global settings.

    Add Internal Network in the Allowed Network for Web Protection global settings.

    If the websites are gettings blocked, do a policy helpdesk test and verify which Filter Action blocks the request. Allow the website from the same.

    Thanks

  • Hi,

     

    I tried what you said but everything you said seems to be set okay. The only thing I can think of is the External (Wan) down interface isn't showing any activity, perhaps I have that configured wrong? I have BT Openreach Fibre to the Cabinet in the UK. Also how will the incoming network traffic know to pass through the UTM, how do UTMs work exactly?

     

    Thanks for your help

  • Are your clients pointing to the UTM  as their default gateway?
    Do you have a masquerading rule configured?

    Is your WAN connection down? In that case you should at least first make sure to have WAN access. You should configure the external interface as is needed by your provider.

  • Hi,

     

    I think the issue is with my WAN uplink but I'm not sure what settings I should enter for my WAN uplink? I don't even know what a WAN uplink is. I have BT Infinity (Fibre to the Cabinet) broadband connection, can you help with the settings? I've also posted the issue on BT's community.

  • Hi,

     

    I didn't really understand that because I'm completely new to networking but thanks for the reply.

  • What most likely could work is to setup your external interface as a DHCP enabled interface so it will get an IP-address from the broadbannd connection. You can then plug the UTM's External interface to the broadband modem and most likely it will get an IP-address.

    If it already has one, than please send us a screenshot of your interfaces screen from the UTM Webadmin.

  • You probably will think I'm really stupid but I'm not sure how to do that.

     

    This is my interfaces screen

  • That is the screenshot I requested. It does only show an Internal interface and not also an external interface.

    Does your UTM machine have at least 2 network interface cards?

  • It has Wi-Fi and Ethernet if that's any help

  • I'm afraid in that case you are missing 1 NIC. For the UTM you need to have at least 2 physical NIC's; 1 for internal and 1 for external.

    The wifi is unusable for this.

  • Why would Wi-Fi not work? It's reliable Wi-Fi. Do you mean it needs two Ethernet ports? Are there many computers that have 2 Ethernet ports?
