Hosts in a branch need to access internet bound services. In traditional deployments, edge routers in branches are connected to the internet via WAN port. To secure the internal network from the internet we have ACLs( Access Control Lists ) to filter the traffic in/out from the WAN port. If we want to filter the traffic into the port we have ingress ACL, egress ACL filters the traffic out of the port. By default, without any ACL configuration present on the WAN port, we accept every traffic coming to the WAN port.
