How to Bypass a Firewall from a Personal Laptop


Part III of How to Bypass a Firewall with the Right VPN Service Provider

Perhaps your work has given you a laptop for work use, or you have your own. Either way, you most likely have user rights to install and configure software on that computer. In this case you have better options open to you. Free proxies can be unpredictable and won't work with some sites (especially those where video is shown); they also tend to be laden with ads and run very slowly. For this reason, you should invest in an anonymous Virtual Private Network (VPN) service. This also operates on the same proxy principle, but is a much more advanced technology (and therefore demands that you have administrative rights for its setup).

What is a proxy connection from a VPN service going to do for you? It's going to encrypt EVERYTHING – not just your content, but your URLs, cookies, all the little revealing packets that slip out of Adobe Flashplayer and Java Applets – I mean everything. This means that not only do you get to bypass the firewall and roam completely free, but also you can be sure that no firewall will have any idea what you are doing. And even if the administrators try to block access to proxies, with the best VPN providers you can choose special-edition IP addresses (called designated IPs – see for more details). These VPNs have even stood the greatest firewall test of them all – unblocking sites from inside the Golden Shield of China.

One caveat about using VPNs for bypassing a firewall… it is possible that the firewall will be set up to disallow personal VPN traffic passing through. PPTP and IPSEC VPNs can be blocked this way. If you subscribe to a high-grade OpenVPN service, however, you will be able to choose to direct your traffic through port 80 or 443. Traffic through these ports are almost never blocked as they carry all browser-based communications (HTTP and HTTPS). However, you must select an anonymous VPN service provider that offers OpenVPN service through port 80 or 443. Many VPN service providers only offer services on the standard OpenVPN port 1194, which can be blocked by firewalls without interfering with browser-based traffic. With the provider selected and the connection established, configuring this switch to open port 80 or 443 on the VPN client software is very straightforward, as long as the software is customized (see idcloak VPN). Any good free anonymous proxy service should offer some form of custom internet privacy software; as well as making the service more user-friendly, it also acts as an effective countermeasure against IP surveillance and internet censorship.

All in all – if you have administrative rights to install software on your PC – a personal OpenVPN service equipped with customized OpenVPN client software is your absolute best answer to the how to bypass a firewall problem.
