Cisco ASA Domain Authentication and Trust (Allowing)
ASA Domain Authentication KB ID 0000973 Problem I cringed this morning when I was asked about this, last time I had to get a client to authenticate to a domain through a firewall, it was ‘entertaining’. The problem is Windows loves to use RPC, which likes to use random ports, so to make it work you either had to open TCP ports 49152 and 65535 (Yes I’m Serious). Or you had to registry hack all your domain controllers...
RSA SecurID Error – ‘106: The Web server is busy. Please try again later’
RSA SecurID Error KB ID 0000975 Problem Not the most descriptive of errors! In fact this has got nothing to do with the busyness of the web server at all. Solution : RSA SecurID Error What’s actually happening is the RSA agent on this machine (in this case a web server) cannot communicate with the RSA Authentication Manager.

Juniper SRX Cluster (Active / Standby)

The problem is they are all geared to setting up a cluster, they ASSUME you then know about security zones, how to add default routes, and setup...
FSSO FortiGate Single Sign On
FSSO KB ID 0001786 If you are applying polices with your FortiGate, e.g. Web Filtering or IPS, then the ability to track actual users rather than IP addresses is advantageous, it’s all very well blocking access to adult material or gambling sites, from the corporate network, but most companies want to know WHO is attempting to connect to what and when. To do that the firewall needs to learn what users are where, we can make...
Cisco ASA Static (One to One) NAT Translation
KB ID 0000691 Problem Note: This is for Cisco ASA 5500, 5500-x, and Cisco Firepower devices running ASA Code. If you have a spare/available public IP address you can statically map that IP address to one of your network hosts, (i.e. for a mail server, or a web server, that needs public access). This is commonly referred to as a ‘Static NAT’, or a ‘One to One translation’. Where all traffic destined for public...
