DESCRIPTION

 

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

This allows you to allocate bandwidth to a route and prioritize traffic that matches

 

Shaping

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

Specify the maximum bandwidth (from 1 to 1048576) allowed for the route in kbps.

 

Bandwidth

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

Enter a number between 1 and 7 to set the priority for traffic. The smaller the

 

Priority

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

Select this check box to have the ZyWALL divide up all of the interface’s

 

Bandwidth Usage

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.

 

 

 

12.3 IP Static Route Screen

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.
