Product: NGAF
Version: 8.0.47
1. Introduction
1.1 Scenario
Configure Sangfor NGAF as the default gateway of two different VLANs (Virtual LANs). In a small Enterprise Network, there are two VLANs (Virtual LANs). By default, they can’t access each other because there is no gateway configured. Sangfor NGAF will act as the gateway for the VLANs (Virtual LANs).

1.2 Other Details
1) The VLANs (Virtual LANs) are VLAN10 (172.16.10.0/ 24) and VLAN20 (172.16.20.0/ 24).
2) The connection between the Access Switch and Core Switch is a trunk interface.
3) The interface of the Core Switch connected to NGAF is also a trunk interface.
4) The IP address of the Desktops are statically assigned.
5) The interface used by NGAF was eth1.
