If you want to direct outbound traffic through the firewall then this traffic will use the outbound IP of the firewall, there is no way to avoid this.
How to force subnet to use a public IP address in a Azure Firewall

I have a Virtual WAN deployed and now added an Azure Firewall. I have a couple of AVD/Citrix environments and I would like to have all traffic go through the Firewall. I also would like to keep the curently used Public IP address in a load balancer for outgoing Internet traffic.
So basically I would like to add a used public IP address in the Azure Firewall and have traffic from a subnet to go out using that public IP address.
Is this even possible or is there some way I can accomplish this.
Thanks
