![]() This allows you to build "transparent" network bridging while still doing firewalling. It will do that for all hosts that it has a direct interface route for. When you switch it on, Sophos UTM will "attract" traffic on that interface for hosts "behind" it and pass it on. By default, the Proxy ARP function is disabled (Off).This option is available on broadcast-type interfaces. Proxy ARP: To enable the function, select the checkbox. ![]() ![]() The metric value is used to distinguish and prioritize routes to the same destination and is valid for all interfaces. By default, an MTU Maximum Tansmission Unit of 1500 bytes is set for the Ethernet interface type.ĭefault route metric: Enter the default route metric for the interface. An MTU size greater than 1500 bytes must be supported by the network operator and the network card (e.g., Gigabit interface). Entering wrong values here can render the interface unusable. Changing this setting should only be done by technically adept users. A sensible value for the interface type is entered by default. You must enter a value fitting your interface type here if you want to use traffic management. MTU: Enter the maximum transmission unit for the interface in bytes. Hostname: If your ISP requires to receive the hostname of your system, enter it here. Optionally, make the following advanced settings: Note – You can configure an interface to have an IPv4 and an IPv6 address simultaneously.Ĭomment (optional): Add a description or other information. IPv4/IPv6 default GW (optional): Select this option if you want to use a statically defined default gateway.ĭefault GW IP (optional): Enter the IP address of the default gateway. Netmask: Select a network mask (IPv4) and/or enter an IPv6 network mask. IPv4/IPv6 address: Enter the IP address of the interface. Please note that one network card cannot be used as both an Ethernet interface and a PPP over Ethernet (PPPoE DSL) or PPTP over Ethernet (PPPoA DSL) connection simultaneously.ĭynamic IP: Activate if you want to use a dynamic IP address. Tip – For an external connection (e.g., to the Internet) choose the network card with SysID eth1. Hardware: Select an interface from the drop-down list. Type: Select Ethernet from the drop-down list. Name: Enter a descriptive name for the interface. On the Interfaces tab, click New Interface. To configure a static Ethernet interface, proceed as follows: To configure a network card for a static Ethernet connection to an internal or external network, you must configure the network card with an IP address and netmask.
