Karim GUIDOUM

Dear Support Team,

my sophos XG has been configured to provide internet access to clients, everything is working well for the client,(internet access, remote SSL VPN)

my issue is that the device didn't ping from the diagnostic page to any address on the internet, also the update firmware is failing,

thank you for helping,

    Hi,

    DNS Settings are OK, clients are accessing internet

    the issue is that  the sophos  device cannot access Internet from the Administration Portal

    Hi : What is the observation in TPCDUMP and Drop packet on XG CLI when you generate PING or any traffic from XG CLI itself? Is it getting dropped or getting forwarded out to the correct WAN Interface?

    please tell us more about IP 192.168.123.81 and 192.168.161.85
    what are these devices? Where are they located?
    If you don't mask your internal traffic at the WAN interface, possible your LAN-segments are routable and the transfer-subnet not..
    Are there other Ways out of your LAN (2nd  ISP, other routers, ...)?

    Try the ping & traceroute 8.8.8.8 tests  again and select the internal interface as source.

    Hi,

    192.168.123.81 is my default GW for the sophos, wich is ISP router, 

    192.168.161.85 is located on the ISP network,

    i'm using NAT with a public IP provided by the ISP, the public IP is configured as an alias on the WAN interface of Sophos firewall

    ping and traceroute to 8.8.8.8.8 using the internal interface as source is also failing,

    i have only one Internet connection

    here is the traceroute screenshot from LAN IP of sohops

    Hi,

    using the public which is assigned to the external interface of your isp router will not work. You need to put the isp router into bridge mode to be able to use the public IP address.
