DESCRIPTION
This field displays when you select Interface in the Type field. Select an
interface to have the ISG50 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 ISG50 automatically disable this policy route when the next hop's
connection is down.
Set how the ISG50 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 299
details.
Select preserve to have the ISG50 keep the packets' original DSCP value.
Select default to have the ISG50 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.
Select none to not use NAT for the route.
Select outgoing-interface to use the IP address of the outgoing interface as the
source IP address of the packets that matches this route. If you select outgoing-
interface, you can also configure port trigger settings for this interface.
To use SNAT for a virtual interface that is in the same WAN trunk as the physical
interface to which the virtual interface is bound, the virtual interface and physical
interface must be in different subnets.
Otherwise, select a pre-defined address (group) to use as the source IP
address(es) of the packets that match this route.
Use Create new Object if you need to configure a new address (group) to use
as the source IP address(es) of the packets that match this route.
Configure trigger port forwarding to allow computers on the LAN to dynamically
take turns using a service that uses a dedicated range of ports on the client side
and a dedicated range of ports on the server side.
Note: You need to create a firewall rule to allow an incoming service before using a
port triggering rule.
Click this to create a new entry. Select an entry and click Add to create a new
entry after the selected entry.
Select an entry and click this to be able to modify it. You can also just double-
click an entry to be able to modify it.
Select an entry and click this to delete it.
The ordering of your rules is important as they are applied in order of their
numbering.
To move an entry to a different number in the list, click the Move icon. In the
field that appears, specify the number to which you want to move the entry.
This is the rule index number.
