With Sophos XG v18 update, there are some significant changes concerning the configuration on selecting a gateway. We will try to explain the changes from v17 to v18 in this article.
How it is in v17:
In v17, you choose the default gateway for the traffic going to the Internet or outside the XG in the same firewall rule configuration. This option was available under Firewall rule Advanced | NAT & routing.
How it is in v18:
Now, let us focus on how we can create the same rule in v18. This is going to be a lot of screenshots but most of them will be set at their default value and you should change it according to your requirement when required. We will create a firewall rule to allow LAN to WAN traffic which should be passed through Port2 primarily and then from WAN link load balance if Port2 is down.
I hope this article helps you understand the difference between v17 and v18. For more information, please check this video guide on YouTube.
