Configuring Avaya CT
In a Firewall Environment
Avaya CT can be configured to function in different firewall environments. (Avaya
CT includes the Tserver and the CVLAN server). This section describes how to
configure Avaya CT when a firewall is placed between the Avaya CT server and
Avaya MultiVantage. See Avaya Computer Telephony, Telephony Services and
Administration and Maintenance Guide for information about other supported
firewall environments.
Requirements for Configuring
Avaya CT in a Firewall Environment
Check with your firewall administrator to determine how your firewall is set up
before you configure Avaya CT.
Option 1: If your firewall manages ports only
If your firewall manages only ports (restricts the source IP address and the
destination IP address to use a specific port), the Avaya CT configuration
requirements are as follows. (See Figure 2-4 on page 2-15)
■ DLG Administration — use standard procedures for both the MAPD DLG
and the Co-Resident DLG, and administer the DLG to point to the IP
Address of the Avaya CT server.
■ G3PD Administration — use standard procedures.
■ Firewall Administration — port 5678 must be open to allow traffic between
the Avaya CT server and the DLG.
Option 2: If your firewall manages ports and IP addresses
If your firewall’s IP address acts as a proxy IP address, the Avaya CT
configuration requirements are as follows. (See Figure 2-5 on page 2-16)
■ DLG Administration — use standard procedures for both the MAPD DLG
and the Co-Resident DLG, and administer the DLG to point to the IP
Address of firewall.
■ G3PD Administration — use standard procedures.
■ Firewall Administration — port 5678 must be open to allow traffic between
the Avaya CT server and the DLG.
