Note: These instructions are intended for version 4.1 of the server. For instructions on versions 5 and 6, see Configuring Connect Professional to listen on additional ports for Connect 6 & 5.x (2405470e). Or, for version 7, see Configure Adobe Connect 7.x to listen on additional ports (cpsid_52631).

By default, Adobe Connect Professional listens on port 1935. It's necessary to open ports 80 and 1935 for the Connect servers in the corporate firewall/proxy as well as the clients (Participants or Presenters).

Sometimes, the client's corporate firewall/proxy server blocks port 1935 for incoming and outgoing network traffic. It's necessary that the client opens port 1935 for incoming and outgoing network traffic to connect to an Adobe Connect Professional meeting. However, sometimes it's impossible for the client to open their corporate firewall/proxy server to accept network traffic on port 1935. Consequently, the responsibility falls on the individual who hosts the Adobe Connect Professional server to properly configure it and open additional ports besides 1935.

If you cannot access Adobe Connect on port 443 or 1935 after following these steps, you can also configure it to communicate on port 80.

The instructions below walk you through how to add another port for Adobe Connect Professional to listen on.

Note:  Still use port 1935, even after adding ports 443 and 80.

To use Connect Presentation and Adobe Connect Professional on a single server that communicates on ports 1935, 443 and 80, use at least two network cards. (It's not a requirement, but with two network interface cards, it can separate the packets on two cards). Also make sure that you have two IP addresses. Assign these two IP addresses a DNS name; each IP address is bound to each network card. Optionally, you could assign two IP addresses to a single network interface card.

The steps below walk you through a sample Connect configuration by modifying the Connect configuration files. This example uses these two IP addresses and128.1.2.4. They are assigned to and, respectively. The NetBios or Full Computer Name of the Connect server is called server-9. (Note: To find out the name of the localhost of the Connect server, type host name and press return in the command prompt. Do not use an underscore in the NetBios or Full Computer Name as it is not supported, a hyphen is acceptable. The ADMIN_HOST (in the custom.ini file) is set to If you are using Network Address Translation (NAT), which means you use private IP addresses, then use the private IP addresses. Don't use the external IP addresses in the Connect configuration files. Adobe Connect Professional requires using the primary IP address. Therefore, it is necessary to set the IP address that is assigned to as the primary address in the Internet Protocol (TCP/IP) in the Local Area Connection.

Next, modify the Connect configuration files to incorporate the ports for Connect Presentation and Adobe Connect Professional.

  1. Open the Windows Services control panel.
  2. Stop Adobe Connect Enterprise Service (formerly Macromedia Breeze Application Service).
  3. Stop Flash Media Administration Server (formerly Flash Communication Admin Service).
  4. Stop Flash Media server (formerly Flash Communication Server).

Modify the following two files:

  • %\Breeze\appserv\conf\SERVER-INF\jrun.xml
  • %\Breeze\custom.ini

Note: Replace % with the drive that you installed Breeze server on. For example, if you installed Breeze on D: drive, use D:\Breeze\custom.ini.

Modify the Connect configuration files:

  1. Open jrun.xml file using any text editor.
  2. Around line 93, locate the following:

    <attribute name="bindAddress">*</attribute>.
  3. Replace the * with the IP address for the Connect Presentation, which is, so that line now looks as follows:

    <attribute name="bindAddress"></attribute>
  4. Save and close jrun.xml.
  5. Open %\Breeze\custom.ini using any text editor.
  6. On a blank line, add DEFAULT_FCS_HOSTPORT and add the IP address for Adobe Connect Professional and the additional ports 1935, 443 and 80. For example:

  7. Copy and paste the following two lines and place them above the line "Congratulations":


    Note: Spell USE_HOST_MAPPINGS in all uppercase, and make sure that there are no spaces between the equal signs. These two lines are case- and space-sensitive. Type everything after the word "yes" in lowercase, including the localhost name of the Connect server.
  8. Save and close custom.ini.
  9. Start Adobe Connect Enterprise Service, Flash Media Administration Server, and Flash Media server, in that order.

To test the new configuration, try logging in to the Connect Manager by launching Microsoft Internet Explorer and enter this URL If you can see the Connect Login screen, Connect Presentation is working. Next, test Adobe Connect Professional by visiting this page You should see the Connect test bandwidth message. If this step does not work, contact Adobe Connect technical support.

Note: Flash Player only tries to detect ports 1935, 443 and 80, so using any other ports doesn't work.
