This article describes an issue wherein an interface of an XG Firewall that uses an IXGBE driver only works if the connected device is set to Auto-negotiate. This is currently observed in the XG 125 and XG 135 models which uses IXGBE driver for ports 1-4. However, the port 5-8 uses IGB driver which does not have an issue even if the connected device is set to manual or auto-negotiate.
Note: The Sophos XG 125 and XG 135 has the port 2 labeled as WAN. However, due to the issue with the IXGBE driver that it uses, port 2 cannot be used as a WAN interface if the connected device is not set to auto-negotiate. The following sections are covered:
