Situation: I have published web services in one of my Wan1 with DNAT/SNAT and I am looking for a way that if my ISP provider of my Wan1 fails, the inbound traffic from Wan2 is automatically redirected. What comes to be a Round Robin. Thank you
Hello José Manuel González García,Thank you for reaching out to the community, in this scenario you may create two separate DNAT rules, so even if one fails you'll be still be able to access it from the another WAN link !> DNAT/Port forward to an internal server: https://support.sophos.com/support/s/article/KB-000035604?language=en_US> Create a source NAT rule: https://docs.sophos.com/nsg/sophos-firewall/18.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/RulesAndPolicies/NATRules/RulesPoliciesCreateSNATRule/index.html

If WAN1 fails ... WAN1 is not reachable for any redirection ...if your app don't try the second DNS-A-record, you need an external DNS-Provider, checking the link availability...
