Cannot Access Internet through Sophos XG (Software) deployed in Gateway Mode

peterforbes

Hi,

I have deployed Sophos XG at home on an old Dell i5 box I had laying around and have it connected in my network as per below.
If I remove Sophos from the Network, my Home LAN devices are all able to obtain IP Addresses just fine. I have tried to add both a DHCP Server and DHCP Relay but cant seem to get it to work. I have tried to use the same Subnet and it still doesnt work. I've also added rules to allow Any from WAN -> LAN and LAN-> WAN.

What am I missing ? 

Thanks in advance, Peter

    Hi,

    Please check if MASQ is applied in the Firewall Rule for LAN-Any-WAN.

    Thanks

      Hi sachingurung,

      Yes I have MASQ on as per below;

      The Interface Configuration for my LAN Port does not show an IPV4 Gateway address, nor am I able to access the Internet as mentioned. I am at a loss :(

      Thanks,

      Peter

        Hi,

        I see NAT=Gateway specific NAT, edit that and selected MASQ in "Use Outbound Address" option.

        What is the IP address defined for XG? Please post an output of "ipconfig /all" for a LAN system. The LAN interface will not show a gateway address as XG is a default gateway.

        Thanks

          Hi Sachin,

          I have tried both of the below changes but still cannot get an IP address on my wireless router.

          I had also thought to include a DHCP Relay back to my cable modem as per below;

          and I still have no luck. ??  :(

          Thanks,

          Peter

            Hi Peter,

            PFA screenshots:

            Configure the DNS IP as 8.8.8.8. Hope that helps.

              Hi Sachin,

              It is now working !   Thank You.

              The only issue I have now is that it is showing my Gateway is down, even though it is up.  :(

              Cheers,

              Peter
