Routing rules

Routing rules consist of a set of criteria determining the path that data packets take from the source to destination across one or more networks. Routing rules are a fundamental aspect of networking, playing a crucial role in determining how data is transmitted between devices on a network.
Once a remote VPN connection is established, the devices connected to LAN 1 become immediately reachable. Instead, the devices connected to LAN 2 are accessible only upon routing rule configuration through
FactoryTalk Remote Access Manager
.

Configuration

To create, modify and cancel static routing rules through
FactoryTalk Remote Access Manager
, access
Explorer
Domain view
 and select a device on the left pane. Then, select
Routing rules
 on the right pane and click on the
circled plus
 button.
The
Create routing rule
 window shows up. It includes three fields:
  1. Subnet IP
    : The subnet that you wish to reach.
  2. Subnet Mask
    : The mask of the subnet that you wish to reach.
  3. Gateway IP
    : The gateway to which any requests to access a specific subnet are forwarded (for example, 192.168.11.113).
You can associate a number of routing rules to a device. They are shown in the
Routing rules
 pane.
In the example shown, one static routing rules has been applied.
NOTE: When a VPN connection is no longer active, the added routing rules are automatically deleted.

Example

To allow the computer providing remote assistance to reach a device on LAN 2 configure a routing rule as per below:
  • Subnet IP: 10.65.0.0
  • Subnet Mask: 255.255.0.0
  • Gateway IP: 192.168.11.113
