Configure Failover (active and backup wan interfaces) on XGS Firewall V19.5

Question

Hellow I am following this configuration for failover: 
 
 https://docs.sophos.com/nsg/sophos-firewall/19.0/Help/en-us/webhelp/onlinehelp/AdministratorHelp/Routing/Gateways/RoutingConfigureGatewayBalancing/index.html 
 
 I want to be sure if there is anything else I need to configure besides what is specifyed on the link, for intance, do we need to set routing or nat, so for when the active link fails it coud nat and route traffic to the backup link? Thanks

Hello Alejandro, 
 
 Good day and thanks for reaching out to Sophos Community and hope you are well. 
 The doc guide in your posted link should be enough given your mentioned use case of configuring failover for active and backup interface, you may use this guide link if you are running 19.5 already - https://docs.sophos.com/nsg/sophos-firewall/19.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/Routing/Gateways/RoutingConfigureGatewayBalancing/index.html#configure-gateway-failover 
 
 Have a nice day and Thank you for choosing Sophos 
 
 Cheers,
