Sophos SG135 WAN side firewall configuration

I have revisited my firewall configuration and have a problem.  I have found that the destination for internet bound traffic on a subnet had been set to all rather than WAN.

This didn't look right so I set the destination for External (WAN) (Network) and promptly broke my connection.  

The primary WAN connection is the Sophos box connection.  I do have a secondary failover connection but this has a very much lower bandwidth and turning it off does not make any difference.  

Please could somebody suggest where I am going wrong and help me sort this out.

Regards,

Budge.

  • Hi Vivek and very many thanks.  I understand now.  As I have it set up all my subnets are configured from the WebAdmin on the UTM.  I have each subnet with a static ip from within a defined range of addresses not relased for dhcp but they use the ip address of the subnet for the gateway and the UTM dhcp for connection to the WAN so from what you say I have it right.  Many thanks.

    So far so good but I have a much bigger problem on which I need help.  Should I continue on this thread or start another?
