There is We now have a new Amahi [http://www.amahi.org/apps/ipsec-vpn IPsec VPNapp] Amahi application fro for your HDA. ! = Introduction =This VPN stack has many advantages, although it still requires two port ports to be forwarded from your router to your HDA. These are
'''500 UDP''' and '''4500 UDP'''
Not UDP, not TCP. Here is how to set up clients for various client operating systems: * [[IPSec VPN iOS Client | iOS]] (iPad, iPhone, iPod) built-in client* [[IPSec VPN Windows Client | Windows 7]]* [[IPSec VPN Mac OS X Client | Mac OS X]] built-in client* [[IPSec VPN Android Client | Android]] built-in client, (ICS, i.e. 4.x or later) The Android (2.x/3.x) OS is known to be broken with respect to [http://www.amahi.org/apps/ipsec-vpn IPSec VPN]. See [[IPSEC/L2TP_VPN_Server|here]] for a manual implementation that should work. '''NOTE:''' By default, the VPN will only route traffic destined for your home network via the VPN. General web traffic etc, will *not* be encrypted. To change this behaviour so that all network traffic from your client is routed via your VPN, edit /etc/racoon/racoon.conf and remove the lines beginning "split_network" and "split_dns". The restart racoon. = Changing Secret and/or Group Name = Optionally, you can change the secret and/or group name. For that, you have to be able to edit a system file as root. Become root via ssh or a terminal and then edit this file: /etc/racoon/psk.txt This file has two field separated by at least one space. The first one is the Group name and the second is the Secret. Change them , keeping in mind that. The changes will be picked up automatically a few seconds later. If you want to make sure, perform a: service racoon restart = Route All traffic through VPN (Amahi 6/Ubuntu) = After you install IPSEC VPN and configure your router and iPhone correctly, you may find that Twitter and Facebook are still blocked by some networks. Also searching for "what is my ip" via Google or your favorite search engine will report back that you are still on the local network. The Amahi VPN is set to use a split VPN tunnel by default. If you want to use blocked services while behind somebody's internet filters, you can use these steps to encrypt your traffic and use blocked services like Twitter and Facebook. Below are the steps to direct all traffic through the VPN. Please note this will divert all of your traffic through your HDA, but you will not be able to access some of your network resources. 1. Open a terminal on your HDA or use SSH.<br /> 2. Go to /etc/racoon. cd /etc/racoon 3. Back up the original racoon.conf in case things break.<br /> cp racoon.conf racoon.conf.orig 4. As root user, open racoon.conf with your favorite editor. sudo nano racoon.conf 5. Go to the line with "mode_cfg".<pre>mode_cfg { auth_source system; save_passwd on; network4 10.8.1.1; netmask4 255.255.255.0; pool_size 10; dns4 192.168.1.10; wins4 192.168.1.10; default_domain "amahi3.com"; auth_throttle 60; split_network include 198.162.1.0/24 10.100.100.0/24; split_dns "home.com"; banner "/etc/racoon/welcome.txt";}</pre> <b>NOTE:</b> Let's concentrate on the two lines that were changed: "split_network" and "split_dns". 6. Change split_network from "include" to "local_lan" and delete the 198.162.... range.<pre>mode_cfg {~~ split_network local_lan 10.100.100.0/24;</pre>

Go 7. Also change "split_dns" to Settings the name that I changed home domain to...<pre> Network mode_cfg {~~ split_dns "amahi3.com";</pre> VPN > IPSec, enter the settings below and click on Save.
