========================================= Multi Interface shaping for a GuestNet ========================================= One of the options with OPNsense's traffic shaper is its ability to add shaping rules based upon two interfaces. This option allows you to shape traffic differently based on the direction the traffic is moving between interfaces. For this example we will use this functionality to share a symmetric 10 Mbps internet connection between a primary LAN network and a Guest Network. The LAN network will not be limited, traffic from users on our Guest Network will be limited to a total of 2 Mbps Download and 1 Mbps Upload. .. nwdiag:: :scale: 100% :caption: Simple network diagram nwdiag { span_width = 90; node_width = 180; Internet [shape = "cisco.cloud"]; Internet -- switchwan; network WAN { switchwan [label="",shape = "cisco.workgroup_switch"]; label = "WAN Interface em1"; fw1 [label="OPNsense", shape = "cisco.firewall", address="172.10.1.1/32"]; } network LAN { switchlan [label="",shape = "cisco.workgroup_switch"]; label = "LAN Interface em0"; address ="192.168.1.x/24"; fw1 [label="OPNsense",address="192.168.1.1/24"]; } pc [label="LAN PC",shape="cisco.pc"]; pc -- switchlan; network GuestNet { switchguestnet [label="",shape = "cisco.workgroup_switch"]; label = "GuestNet Interface em2"; address ="192.168.2.x/24"; fw1 [label="OPNsense",address="192.168.2.1/24"]; } laptop [label="Guest Laptop", shape="cisco.laptop"] laptop -- switchguestnet; } Step 1 - Create Upload and Download Pipes ----------------------------------------- On the **Pipes** tab click the **+** button in the lower right corner.
