Cisco Secure ACS 4.2 will not replicate through firewall

Postby admin » Wed Oct 24, 2012 1:16 pm

If your two Cisco Secure ACS 4.2 servers will not replicate through a Cisco ASA firewall, try changing the tcp port it uses. I found that TCP port 2000 (The default port), it would fail. I changed it to TCP 2012 (I just picked one with in the allowed range) and it worked great.

This assuming you have followed the configuration steps in the configuration guide to setup replication.
If you have not, follow the directions on the following link.
http://www.cisco.com/en/US/products/hw/ ... procedures

Here are the directions to change the TCP port, do this on both servers.

1. Interface configuration --> Advanced Options --> Check the "checkbox ACS Communication Port Configuration".
2. System Configuration --> service control --> Configure the Port to be used for the ACS Internal Communication (The range is between 2010 to 2025)

For a list of common TCP ports and their use, check out this link.
