After initial setup, no Internet access (includes diagram)

Hi all

 

I have set up Sophos XG Home on a supported Qotom mini PC. Per my diagram I can login to the XG, configure it but no LAN device can get access to the Internet. The Sophos Control Center has the Interface icon in red with an exclamation mark.

It's in Bridge Mode, LAN Port 1 is connected to the modem/router and LAN Port 2 is connected to the LAN switch.

 

What have I missed?

    

Thanks

  • Sorry, link to diagram mightn't work so here it is...

  • Hi Peter,

    very simple, you don't have any rules allowing traffic out. Why do you have your wifi point on the outside of the XG, I know it is part of your modem/router?

  • Hi rfcat_vk

     

    Re the WiFi, wifi is disabled on the router

    Can you help me with the rule I need please, the one I have in there is not correct I assume?

  • Hi Peter,

    the rule could be any zone (source) any to any zone destination any -> allow all. What I can't see is your MASQ (NAT) rule.

    Next question is why are you using the modem as gateway rather than bridged mode and have the XG be the true gateway and only one NAT.

    Which device is providing your DHCP function?

  • rfcat_vk

     

    The modem/router is providing DHCP. Are you saying I should disable all routing functions from the device and use the XG to be DHCP, NAT etc etc?

  • Hi Peter,

    that would make debugging easier and filter creation simpler.

  • i have same config as you, here are my two rules (one for in and one for out).

    Also don't enabled MASQ as it can affect some of those layer 2 packets that are non routable, for example it broke some of the discovery i needed for my router control SW and IMO isn't needed in this scenario

     

    here is the summary of the bottom rule as an example, hope that helps.

    Summary

    All Inbound

    Allow

    Rule

    Accept any service going to "LAN" zone, when in "WAN" zone, and coming from any network, scan for malware then check with Sandstorm and log connections, then apply IPS policies

    Source Networks and Devices : Any
    During Scheduled Time : All the Time

    Destination & Services
