Chapter 13 Trunks The following table describes the items in this screen. Table 84 Configuration > Network > Interface > Trunk LABEL Show Advance Settings / Hide Advance Settings Enable Link Sticking DESCRIPTION Click this button to display a greater or lesser number of configuration fields. Enable link sticking to have the system route sessions from one source to the same destination through the same link for a period of time. This is useful for accessing server that are incompatible with a user's sessions coming from different links. For example, this is useful when a server requires authentication. Timeout Passive Connection Disconnect Enable Default SNAT Default Trunk Selection for Forwarding Traffic Default Trunk Selection for System Service Traffic User Configuration System Default Add Edit Remove Object References # Name Algorithm Apply Reset This setting applies when you use load balancing and have multiple WAN interfaces set to active mode. Specify the time period during which sessions from one source to the same destination are to use the same link. Select this to drop a passive mode interface's connections when the trunk's active mode interface comes back up. Select this to have the ISG50 use the IP address of the outgoing interface as the source IP address of the packets it sends out through its WAN trunks. The ISG50 automatically adds SNAT settings for traffic it routes from internal interfaces to external interfaces. Select the WAN trunk the ISG50 uses for routing traffic going through the ISG50. Select the WAN trunk the ISG50 uses for routing traffic originating from the ISG50 itself. This includes the PBX traffic. The trunk can only have one member interface set to active mode. You can create your own User Configuration trunks. The ISG50 automatically adds all external interfaces into the pre-configured system default SYSTEM_DEFAULT_WAN_TRUNK. You cannot delete it. Click this to create a new user-configured trunk. Double-click an entry or select it and click Edit to open a screen where you can modify the entry's settings. To remove a user-configured trunk, select it and click Remove. The ISG50 confirms you want to remove it before doing so. Select an entry and click Object References to open a screen that shows which settings use the entry. See Section 12.3.2 on page 246 for an example. This field is a sequential value, and it is not associated with any interface. This field displays the label that you specified to identify the trunk. This field displays the load balancing method the trunk is set to use. Click this button to save your changes to the ISG50. Click this button to return the screen to its last-saved settings. 286 ISG50 User's Guide
