    Hi ,

    Thank you for reaching out to the Community! 

    I assume you already have Dynamic DNS configured on your firewall. 

    On the site that is initiating the connection, add the Dynamic DNS of the peer firewall under the remote gateway. You also need local and remote ID configured, add remote firewalls WAN IP as remote ID and WAN IP ass local ID on the local firewall. 

    On the remote firewall, add "*" under the remote gateway and configure local and remote ID. 

    Let us know how it turns out for you.

    Thanks,

  • Hi H_Patel ,

    Thanks for Replay , in m'y case Sophos Can résolve the fqdn i can find the IP addres but i can't ping it and the the web admin can't be Access from the WAN , with the device Access IS enabled from WAN (HTTPS and ping ) 

    Now i know the problème IS I have a modem with sim Data for accèss to internet .

    Sophos have a address 192.168.0.200 get it from the modem 

    I allso open the port 443 in the modem and allow ping and open the port 4444 for administration sophos , and i forwarding the port 4444 in the modem to sophos xg 

    I juste create a rule in modem to forward .
