In this article, we take a look at the configuration steps to set up High Availability between two Cisco Secure Firewalls running ASA software using the command line interface (CLI) with a shared dedicated physical link for the Failover and Stateful Link features.
In this article, I’ve compiled a base configuration to be used for setting up new Cisco Adaptive Security Appliances, or ASAs for short, and included some pointers on which other configuration steps are necessary to get most typical deployments up and running.
In this article, we take a look at the common fix for getting Cisco ASDM running when you run into the “This app can’t run on your PC” error message. This error is somewhat normal to run into these days to due changes in the Windows operating system.
In this article, we take a look at the open-source OpenConnect VPN client software and test it out in some different VPN-configurations, mainly connecting to different Cisco firewalls, and doing some light comparisons to how it stacks up against Cisco’s AnyConnect VPN software.
Cisco firewalls running the (now) old operating system ASA are dependent on Java to run a software called ASDM, which is the GUI-application used to manage the firewall. However, in this day and age, it is getting increasingly harder to have the correct Java version installed to install ASDM on your computer. Throughout the years there has always been one workaround to access ASDM even without installing it and it has worked for me in my most desperate times.
This article cover some good things to know when it comes to configuring a Cisco ASA remote-access VPN that uses SAML-authentication to identify and authenticate users. SAML-authentication is something most network administrators rarely run into but in this single sign-on era you can except to see more of it and sometimes it’s not obvious what parameter needs to go where.
A lot of Cisco ASA administrators run into issues when trying to access the ASA itself over a Remote-Access VPN or Site-to-Site VPN tunnel due to the odd traffic path and in this article, we take a look at some of the fixes you might need to apply to make this all work.
