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 google-ing "what is my ip" will report back that you are still on the local network.
It turns out that the 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 ssh in. 2 - go # Go to /etc/racoon (that is spelled correctly BTW)
{{Code| cd /etc/racoon}}
3 # Back- up the original racoon.conf in case things break# As root, open racoon.conf with your favorite editor, mine happens to be nano (this needs to be done as root)
{{Code| sudo nano racoon.conf}}
4 - # down arrow to the mode_cfg
{{Code| mode_cfg {
auth_source system;
}}
note: I'm going to concentrate on the two lines that I changed: "split_network" and "split_dns".
5 # - change split_network from "include" to "local_lan" and delete the 198.162.... range.
{{Code| mode_cfg {
~~
split_network local_lan 10.100.100.0/24;
}}
6 # - I also changed split_dns to the name that I changed my home domain to...
{{Code| mode_cfg {
~~
split_dns "Jamahi3.com";
}}
7 # - save your work 8 # - restart the racoon server
{{Code| sudo service racoon restart
}}
Or - open up your hda, click on settings>servers and restart the IPSEC server.
Googling "What is My IP" should now report your home VPN. You should then be able to use twitter and facebook through your VPN.
