# VpcEndpoint
<a name="API_VpcEndpoint"></a>

The VPC and subnets for a proxy mode firewall endpoint. This is used in [CreateFirewall](API_CreateFirewall.md) when `NoSourcePreservation` is `TRUE`, to specify where Network Firewall creates the firewall endpoint. 

This differs from [VpcEndpointAssociation](API_VpcEndpointAssociation.md), which defines additional secondary endpoints for a firewall in other VPCs.
