Chapter 15 Policy and Static Routes Table 82 Configuration > Network > Routing > Policy Route > Edit (continued) LABEL DESCRIPTION VPN Tunnel This field displays when you select VPN Tunnel in the Type field. Select a VPN tunnel through which the packets are sent to the remote network that is connected to the ZyWALL directly. Auto Destination Address This field displays when you select VPN Tunnel in the Type field. Select this to have the ZyWALL use the local network of the peer router that initiated an incoming dynamic IPSec tunnel as the destination address of the policy. Trunk Interface AutoDisable DSCP Marking DSCP Marking Leave this cleared if you want to manually specify the destination address. This field displays when you select Trunk in the Type field. Select a trunk group to have the ZyWALL send the packets via the interfaces in the group. This field displays when you select Interface in the Type field. Select an interface to have the ZyWALL send traffic that matches the policy route through the specified interface. This field displays when you select Interface or Trunk in the Type field. Select this to have the ZyWALL automatically disable this policy route when the next hop's connection is down. Set how the ZyWALL handles the DSCP value of the outgoing packets that match this route. Select one of the pre-defined DSCP values to apply or select User Defined to specify another DSCP value. The "af" choices stand for Assured Forwarding. The number following the "af" identifies one of four classes and one of three drop preferences. See Assured Forwarding (AF) PHB for DiffServ on page 359 for more details. Select preserve to have the ZyWALL keep the packets' original DSCP value. UserDefined DSCP Code Address Translation Select default to have the ZyWALL set the DSCP value of the packets to 0. Use this field to specify a custom DSCP value. Use this section to configure NAT for the policy route. This section does not apply to policy routes that use a VPN tunnel as the next hop.
