+## Purpose
+You may have a Sophos XGS appliance and need more than one interface to act as additional LAN ports.  You can achieve this with bridges.
+
+!!! info "Assumptions"
+    It is assumed that your Sophos XGS appliance has at least 3 interfaces, one for `WAN`, one for `LAN`, and a third one that will act as a member of the bridge.  You can have as many member interfaces of the bridge as needed, but you need at least one.
+
+## Login to the Firewall
+You will need to access the firewall either directly on the local network at `https://<IP-of-Firewall>:4444` or remotely in Sophos Central.
+
+## Configure a LAN bridge
+Navigate to "**Configure > Network > Interfaces > "Add Interface" > "Add Bridge"**"
+
+| **Field** | **Value** |
+| :--- | :--- |
+| Name | `LAN Bridge` |
+| Hardware | `br0` |
+| Enable routing on this bridge pair | `<Unchecked>` |
+| Member Interfaces | `<Interfaces-of-Additional-Ports> / Zone: "LAN"` |
+
+!!! warning
+    The LAN interface itself needs to be a member of the bridge.  If it is not, the Sophos Appliance will not allow you to use the same IP address as the existing LAN interface.
+
+### IPv4 Configuration
+| **Field** | **Value** |
+| :--- | :--- |
+| IP Assignment | `Static` |

+| Gateway IP | `<Blank>` |
+| Member Interfaces | `<Interfaces-of-Additional-Ports> / Zone: "LAN"` |
