Install Quagga As Linux Router. Because the curious how to make Router in Linux, I was browsing to search for how to install Linux on the router using the quagga.
After finding several blogs and the web of quagga load …. finally I make a summary and conclusions of how to install the router quagga. This posting only as a reminder, because my type of forgetful. In this post I use the Ubuntu Linux distribution, because it is more practical and effective. Let’s see at the following description…. enjoy. IPv6 Firewalling - SixXS Wiki. This article is for information regarding firewalls on an IPv6 network.
Please see the SixXS FAQ for some information on what one should filter. Linux support Linux Kernel (ip6tables) There is now an IPv6 stateful inspection kernel module since version 2.6.20 and ip6tables version 1.3.5 [1] [2]; you will need to enable the kernel module named CONFIG_NF_CONNTRACK_IPV6. Configurable scripts You don't have to build a specialized script for every firewall; there are configurable ones. Beginning with Shorewall version 4.2.4, there are two additional packages that provide IPv6 support that can be installed to ipv4 Shorewall in parallel. shorewall6, is documented at shorewall6 6wall, much like the example script below, is ready for old kernels (up to 2.6.20) that do not support properly IPv6 connection tracking. If you are running Linux 2.6.21+, you can apply a patch to add proper connection tracking support. Using upstart on Ubuntu without additional packages Save and restore IPv6 firewall rules #!

With the previous articles we got our main network connected to the IPv6 Internet.
But what about Laptops that are used off-site? Here I'll show how to use a VPN to tunnel IPv6 from any point in the IPv4 network into your main IPv6-enabled network. OpenVPN is a fairly simple to configure secure VPN software that runs on all Unix-like systems, MacOS/X, and Windows. It is much more simple to configure than IP/Sec and as secure. In the following paragraphs I'll concentrate on the things that are important to understand to get IPv6 running over OpenVPN, I'll skip the more interesting parts of OpenVPN internals - the OpenVPN Documentation does a better job at that than I ever could. I also concentrate on Linux configuration here - other Unix-like systems and MacOS should behave similarly. Basics First we need to get OpenVPN installed. Apt-get install openvpn I'll assume that the OpenVPN package installs its configuration in /etc/openvpn/. Next we need to generate a key: Tun versus Tap Server #!
#! How to setup an IPv6-only network with NAT64, DNS64 and Shorewall » Philippe Dellaert. How to setup an IPv6-only network with NAT64, DNS64 and Shorewall September 23, 2012 in Guides, Linux The goal of this article is to help people to set up a network that is IPv6 Only (except for the gateway) and does allow the users to access IPv4 servers beyond the gateway.
If you follow the news surrounding the IPv4 exhaustion, you will now that IPv4 is running out of space rapidly (currently Ripe is allocating the last /8 address space). So, it’s time to start thinking about moving to IPv6. I have been using a 6-in-4 tunnel from Sixxs for a couple of years now, using this i have set up a dual stack network with my own /48 subnet. I’ve been using this setup for a while now, and thou it’s an improvement on getting ready for IPv6, it still has an IPv4 network as well. To solve this, i decided to configure an IPv6 only network in a test environment, using NAT64 and DNS64. I’m using this guide as a form of documentation.
