Enabling Egress FQDN for Public Subnet Filtering Gateway (Legacy)

Once the PSF gateway is launched, you can configure the Egress FQDN (Legacy) feature. Egress FQDN (Egress Control Filter) is a legacy FQDN feature applied to the public subnets.

Only use this tool if you have not purchased and enabled the DCF feature.

In the Aviatrix Controller, navigate to Security > Egress Control and follow the instructions in the FQDN workflow.

Public Subnet Instances and FQDN

When you enable Egress FQDN (Legacy) filtering for public subnets, packets initiated from the instances on the public subnet do not get NATed when going through the FQDN filtering gateway, and the source public IP address of a public subnet instance is preserved.
