ZyWALL USG 100/200 Series User’s Guide

Click Network > Routing > Static Route to open the Static Route screen. This screen 
displays the configured static routes. Configure static routes to be able to use RIP or OSPF to 
propagate the routing information to other routers.

Incoming Service

Select the service that the client computer sends to a remote server. 
The incoming service should have the same service or protocol type as what you 
configured in the Service field.

Trigger Service

Select a service that a remote server sends. It causes (triggers) the ZyWALL to 
forward the traffic (received on the outgoing interface) to the client computer that 
requested the service.

Add icon

Click the Add icon in the heading row to add a new first entry.
Click the Add icon in an entry to add a rule below the current entry.
Click the Remove icon to delete an existing rule from the ZyWALL. A window 
displays asking you to confirm that you want to delete the rule.
In a numbered list, click the Move to N icon to display a field to type a number for 
where you want to put that rule and press [ENTER]

 

to move the rule to the number 

that you typed.
The ordering of your rules is important as they are applied in order of their 
numbering.

Bandwidth 
Shaping

This allows you to allocate bandwidth to a route and prioritize traffic that matches 
the routing policy. 
You must also enable bandwidth management in the main policy route screen 
(Network > Routing > Policy Route) in order to apply bandwidth shaping.

Maximum 
Bandwidth

Specify the maximum bandwidth (from 1 to 1048576) allowed for the route in kbps. 
If you enter 0 here, there is no bandwidth limitation for the route.
If the sum of the bandwidths for routes using the same next hop is higher than the 
actual transmission speed, lower priority traffic may not be sent if higher priority 
traffic uses all of the actual bandwidth.
To reserve bandwidth for traffic that does not match any of the policy routes, leave 
some of the interface’s bandwidth unbudgeted and do not enable Maximize 
Bandwidth Usage.

Bandwidth 
Priority

Enter a number between 1 and 7 to set the priority for traffic. The smaller the 
number, the higher the priority. If you set the maximum bandwidth to 0, the 
bandwidth priority will be changed to 0 after you click OK. That means the route 
has the highest priority and will get all the bandwidth it needs up to the maximum 
available.
A route with higher priority is given bandwidth before a route with lower priority. 
If you set routes to have the same priority, then bandwidth is divided equally 
amongst those routes.

Maximize 
Bandwidth Usage

Select this check box to have the ZyWALL divide up all of the interface’s 
unallocated and/or unused bandwidth among the policy routes that require 
bandwidth. Do not select this if you want to reserve bandwidth for traffic that does 
not match any of the policy routes.

OK

Click OK to save your changes back to the ZyWALL.

Cancel

Click Cancel to exit this screen without saving.
