D-Link DFL-2500 - Manual (Page 66)

1. In the address book set up the following IP objects:
• remote_net_A: 192.168.10.0/24
• remote_gw: 172.16.0.1
• ip_GRE: 192.168.0.2
2. Create a GRE Tunnel object called GRE_to_A with the following parameters:
• IP Address: ip_GRE
• Remote Network: remote_net_A
• Remote Endpoint: remote_gw
• Use Session Key: 1
• Additional Encapulation Checksum: Enabled
3. Define a route in the main routing table which routes all traffic to remote_net_A on the
GRE_to_A GRE interface. This is not necessary if the option Add route for remote network
is enabled in the Advanced tab, since this will add the route automatically.
4. Create the following rules in the IP rule set that allow traffic to pass through the tunnel:
Name Action Src Interface Src Network Dest Interface Dest Network Service
To_A Allow lan lannet GRE_to_A remote_net_A All
From_A Allow GRE_to_A remote_net_A lan lannet All
3.3.6. Interface Groups
Multiple NetDefendOS interfaces can be grouped together to form an Interface Group. Such a
logical group can then be subject to common policies and be referred to using a group name in the
IP rule set and User Authentication Rules.
A group can consist of regular Ethernet interfaces, VLAN interfaces, or VPN Tunnels and the
members of a group need not be of the same type. A group might consist, for instance, of two
Ethernet interfaces and four VLAN interfaces.
Example 3.13. Creating an Interface Group
CLI
gw-world:/> add Interface InterfaceGroup examplegroup Members=exampleif1,exampleif2
Web Interface
1. Go to Interfaces > Interface Groups > Add > InterfaceGroup
2. Enter the following information to define the group:
• Name: The name of the group to be used later
• Security/Transport Equivalent: If enabled, the interface group can be used as a destination interface in
rules where connections might need to be moved between the interfaces - examples of such usage are
Route Fail-Over and OSPF
• Interfaces: Select the interfaces to be in the group
