Azure Firewall behind public load balancer configuration
Hi, I have a requirement to replace Sophos firewall with Azure Firewall Premium. The existing Sophos firewall is behind a public Azure load balancer (backend pool comprises the Sophos Firewall IP...
jameswonderguythis is not a valid config and it does not make any sense to be honest. You can't put Azure firewall in LB backend pool and you can only add private IPs or NICs from the same LB VNET to the backend pool.
Why would you want to put the firewall behind a load balancer in the first place? The FW has a public front end IP that you can use for incoming traffic from internet and and a private IP for the traffic coming from the local VNET or peered VNETs. There is no need for the load balancer at all.
- anas86, Thank you for your response! I was able to set up the Azure Firewall to accept incoming and outgoing traffic.

jameswonderguy What was your final setup like - given you had a public load balancer?
