Creating a tunnel between two Business Communications
Managers
The following is an example of a how to connect two Business Communications Manager systems
together using an IPSec tunnel.
In this example, the IPSec tunnel connects a Business Communications Manager with a LAN 2 IP
address of 10.10.11.1 and another Business Communications Manager with a LAN 2 IP address of
10.10.11.2. LAN 1 on the first Business Communications Manager is on the subnet 12.12.12.0.
The LAN 1 of the second Business Communications Manager is on subnet 14.14.14.0.
Configuring the first Business Communications Manager
1 Set the Local Endpoint to 10.10.11.1 .
2 Set the Remote Endpoint to 10.10.11.2 .
3 Set the Preshared Key to 123 .
4 Set the Key Type to Text .
5 Set the Local Accessible Networks to 12.12.12.0 with mask 255.255.255.0 .
6 Set the Remote Accessible Networks to 14.14.14.0 with mask 255.255.255.0 .
Configuring the second Business Communications Manager
1 Set the Local Endpoint to 10.10.11.2 .
2 Set the Remote Endpoint to 10.10.11.1 .
3 Set the Preshared Key to 123 .
4 Set the Key Type to Text .
5
Set the Local Accessible Networks to 14.14.14.0 with mask 255.255.255.0 .
6 Set the Remote Accessible Networks to 12.12.12.0 with mask 255.255.255.0 .
On the Global settings for both Business Communications Manager systems, set the Status to
