Introduction

A route describes the path that a packet takes to get from its source to the desired destination.

Default-Route

The default route is the path from the desired source to the destination Internet 0.0.0.0/0

It describes the path if no other route is found for the packet sent out.

Adding a new default route: Network Network configuration Area Routing Button Add default route			Network configuration UTMuser@firewall.name.fqdnNetwork
In the Add Default Route dialog, one of the two options is selected
Caption	Value	Description	Default-Route hinzufügen UTMuser@firewall.name.fqdnNetworkNetwork configuration
Gateway Type:	IPSchnittstelle	Der Typ des Gateways
Gateway:	LAN3	The interface of the gateway
IPv6:	Off	When enabled On IPv6 is used
Click Save and close to apply this setting and close the window.

The newly created default route is then displayed in this list. Under Gateway either the entered IP address, or the selected interface is displayed. The default destination is always 0.0.0.0/0, the weighting by default 0. Edit Opens the dialog to edit the route For a default route, only change the weighting. Delete Opens the dialog to delete the route			Network configuration UTMuser@firewall.name.fqdnNetwork

Route

The path of a packet can be precisely defined via a route. This allows two different interfaces to communicate with each other.

Unter Network Network Configuration Area Routing Button Route hinzufügen wird eine neue Route hinzugefügt.			Network configuration UTMuser@firewall.name.fqdnNetwork
In the new window Add route the following settings are made.
Caption	Value	Description	Route hinzufügen UTMuser@firewall.name.fqdnNetworkNetwork configuration
Source network:	192.168.175.0/24	Optional The IP address of the source
Gateway Type:	IPSchnittstelle	Der Typ des Gateways
Gateway:	LAN1	The interface of the gateway
Target network:	0.0.0.0/0	The IP address of the destination
Weighting:	0	Priority of use of this route
Click Save and close to apply this setting and close the window.
In the example route created above, all clients from the source network 192.168.175.0/24 are routed to the destination 0.0.0.0/0, i.e. the Internet, via the gateway interface LAN1.

In the following lower route, all clients from the source network 192.168.176.0/24 are routed to the destination 0.0.0.0/0 via the gateway IP 203.0.113.113/24.

Source network:	192.168.176.0/24	Optional The IP address of the source	Route hinzufügen UTMuser@firewall.name.fqdnNetworkNetwork configuration
Gateway Type:	IPSchnittstelle	Der Typ des Gateways
Gateway:	203.0.113.113/---	IP-Adresse des Gateways In diesem Beispiel liegt eine öffentliche IP-Adresse an einer Schnittstelle an
Target network:	0.0.0.0/0	The IP address of the destination
Weighting:	0	Priority of use of this route
Click Save and close to apply this setting and close the window.

The newly created route is then displayed in this list. The Source of this route, as the Gateway, either the entered IP address, or the selected interface is displayed. As destination the IP address of the route destination and as weighting the route priority.

Route Hint

Network configuration UTMuser@firewall.name.fqdnNetwork This default route is also a route hint. All created routes via gateway LAN1 are routed to the destination via its IP address. A Route Hint simplifies the configuration of routes and is even necessary for some configurations. A route is created by selecting the desired gateway interface and entering the destination network. The source network remains free. Any further route that has this gateway interface will always be routed to the set destination network, using its gateway IP address.
