Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I understand that you would like to NAT a private Traffic in Azure VNETs.
You can consider using the SNAT feature of Azure Firewall to NAT RFC 1918 traffic in Azure VNET .
Refer : Azure Firewall SNAT private IP address ranges
- Note: The NAT will be performed to one of the Private IP ranges in the FirewallSubnet Or you could use a custom NVA as you have mentioned to perform the NAT.
Hope this helps.
Thanks,
Kapil
