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

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,

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
