Interfaces

1 Introduction

WFilter NGF can act as a gateway or network bridge.

• A network bridge can be deployed transparently with no changes to your existing network. Most features are available in bridge mode.
• In gateway deployment, all features are available, including VLAN, port forwarding, VPN... which are not available in bridge mode.

2 Gateway Deployment

Gateway deployment: WFilter NG Firewall acts as the gateway for local nework. Usually, your current gateway shall be replaced with WFilter NG Firewall. Network diagram:

2.1 WAN

• Protocol: PPPoE, DHCP, static IP.
• Peer DNS: Use the dynamic assigned DNS server in PPPoE and DHCP protocols. If disabled, use the DNS servers configured in "DNS" instead.
• MAC Clone: Modify the MAC address of this WAN interface.
• VLAN ID: Enable 802.1q VLAN in this WAN interface.

2.2 LAN

• You can have different subnet in every LAN interface. Or all LAN interfaces share a same subnet.
• Each LAN interface can have a DHCP service.
• When IP-MAC Binding is enabled, clients will always be assigned with the bound IP via DHCP service.

2.2.1 DHCP Options

• In default, DHCP gateway and dns server are all configured as WFilter's lan ip address.
• In case you need to modify the default DHCP options, the syntax is "DHCP code,Value"(one option per line). For examples:
  • 3,192.168.1.1(default gateway)
  • 6,8.8.8.8(default dns server)

3 Bridge Deployment

Bridge Deployment: Build network bridge(s) on certain interfaces. With bridge deployment, you can transparently deploy WFilter, without changing current network topology. Network diagram:

3.1 Settings

• Each bridge has one LAN interface and one WAN interface.
• You can build multiple bridges if needed.
• You can setup a management interface to access web UI.

• Management Interface:
  • The management interface is for web UI access, web authentication UI access...
  • IP, Mask: IP, Mask of the management interface.
  • Gateway: Gateway of the mangement interface. WFilter needs a gateway to access interface to get updates.
  • Subnet(s): local subnets to be managed. Syntax: 192.168.1.0/24, one subnet per line. "-" starts a subnet exception, for example: "-192.168.1.20/32".

You can build new bridges from "undefined interfaces". For new bridges, you only need to configure LAN & WAN interfaces.
