Cisco ASA Identity Firewall. December 18, 2013. Testing at the moment identity firewalling with a Cisco ASA for a new office network infrastructure. From the configuration everything is straight forward and easy to set-up: 1. Configure AAA LDAP Server. If you use ldap over SSL you need to enable it and change the server port! 2 Configure Windows Cisco AD Agent. Install the Cisco AD Agent on one of your Windows Servers, not the Domain Controller if you also want to use NPS! 3 Configure AG Agent on the ASA.

May 29, 2014. Something a bit different now from what I posting normally, this time about common DNS errors. One of colleagues tried to configure basic DNS load balancing over two web platforms but instead of using two A records he were using one A record and one CNAME. Ones that was configured the problems started because some DNS server (google DNS cache) were only replying with the IP of the configured CNAME, other DNS servers from service providers were replying with nothing.
