Cisco ASA Remote Access VPN for Android

The native Android IPsec VPN client supports connections to the Cisco ASA firewall. This even works without the “AnyConnect for Mobile” license on the ASA. If only a basic remote access VPN connection is needed, this fits perfectly. It uses the classical IPsec protocol instead of the newer SSL version. However, the VPN tunnel works anyway.

In this short post I am showing the configuration steps on the ASA and on the Android phone in order to establish a remote access VPN tunnel.

Palo Alto Remote Access VPN for Android

For a basic remote access VPN connection to a Palo Alto Networks firewall (called “GlobalProtect”), the built-in VPN feature from Android can be used instead of the GlobalProtect app from Palo Alto itself. If the additional features such as HIP profiling are not needed, this variant fits perfectly.

I am showing a few screenshots and logs from the Android smartphone as well as from the Palo Alto to show the differences.

Juniper Secure Access: Easy Deployment Poster

For a beginner, the configuration of a Juniper Secure Access SA/MAG device is not that simple. There are too many options and links that must be filled in. Though there are quite detailed configuration guides I was missing a “quick start” figure to see which profiles, roles, etc. must be set in order to have a simple login and group membership environment.

Here comes my at-a-glance poster for the Junos Pulse Secure Access Service (SSL-VPN).

Palo Alto Remote Access VPN for iPhone

I tested the Palo Alto GlobalProtect app on my iPhone, but also the native IPsec Cisco VPN-Client on iOS which connects to the GlobalProtect Gateway on a Palo Alto firewall, too. Since this variant needs no further licenses from Palo Alto, it is a cheap alternative for a basic VPN connection.

Though not that much exciting, there are a few differences in the logs on the firewall which I will show here on the basis of a few screenshots.

Palo Alto GlobalProtect for Linux

Palo Alto GlobalProtect for Linux with vpnc

This is a tutorial on how to configure the GlobalProtect Gateway on a Palo Alto firewall in order to connect to it from a Linux computer with vpnc.

Short version: Enable IPsec and X-Auth on the Gateway and define a Group Name and Group Password. With this two values (and the gateway address), add a new VPN profile within vpnc on the Linux machine. Login with the already existing credentials.

Long version with screenshots comes here:

Cisco AnyConnect: IPv6 Access through IPv4 VPN Tunnel

When traveling to guest Wifis, e.g., at different customers sites, hotels, or public Wifis in general, I often have only IPv4 access to the Internet. Since I do not want to use IPv6 tunneling protocols such as Teredo, I decided to use the Cisco AnyConnect Secure Mobility Client to tunnel IPv6 between my test laboratory (Cisco ASA) and my computer. With a few changes on the ASA, my computer now gets a private IPv4 address and a global unicast IPv6 address out of my space at home. Since I am using a VPN tunnel to access the Internet from untrusted Wifis anyway, the overall process did not change that much.

In the following I am showing a few screenshots but not a complete configuration guide for the AnyConnect Client.
