1. Click on SETTINGS and then choose Openweb Options.

2. In Tunnel mode, you can choose whether to tunnel only web browsers (Browsers) or all applications (All Apps).

3. In Port, port is set to 443 by default. You can change it to 80, ALTA or ALTB (alta and altb can be random port assigned by server) and see which one works for you.

4. In Protocol, ver2 (version 2) is for users where ISP throttles torrents and unknown traffic. Some antivirus software is confused with Openweb ver2 protocol, so it will break it. In such case, you can use ver 1 (version 1).

5. Auto Tunnel Apps. When this option is enabled, Astrill will use system-wide Network Redirector Component to tunnel web traffic from applications automatically. No need to set system proxy. This option works with all major web browser.

6. Set System Proxy. Sets system global proxy automatically when Astrill is enabled. This affects all applications which use system proxy setting. This option is disabled by default. In case "auto tunnel apps" does not redirect your application automatically, try to enable this option.

7. Show logo in Firefox. This shows Astrill logo in Firefox address bar when Astrill is enabled.

Advanced Options

Advanced options will allow you to toggle on/off settings and features.

1. Advanced Option is under Settings

2. Keep connection – This option lets you keep connection even when you switch to another Astrill server (from drop-down list) or when you turn Astrill OFF (using ON/OFF button). This is especially useful when you are downloading a file and want to switch to another server. Normally Astrill would disconnect all connections thus your download would be aborted. With this new option you can change this behavior.

3. Auto CLear Cookies - this option, when checked, will tell Astrill to clear all browser and Flash cookies whenever you switch to another sever or turn Astrill ON or OFF. This is very useful for some web sites which remember you using cookies, so even if you are using VPN, they will know your default location. We have also added an option to the tray/context menu “Clear Cookies” which you can use to manually clear all cookies whenever you wish. This is very convenient too as it clears nasty Flash Cookies which are normally very hard to remove (you would need to go to Adobe web site to do that). When we are at explaining how sites tracking your location by cookies, let’s mention that some sites (like track your timezone as well ! Thus even if you are using VPN, that site will show you are not in USA and will not let you watch any videos. This is very easy to fix – just set your system timezone to let’s say UTC-8 which is California time zone. (you might need to restart browser or refresh the page – Ctrl-F5)

4. Stream Flash Directly – this option tries to stream flash videos directly (without VPN). Some sites don’t check location when streaming (Hulu is an exception tho). Thus using this option you can speed up your video streaming but usually our VPN is very fast thus you will not notice any difference.

5. Video Accelerator – this option enabled a special component in Astrill which accelerates video streaming thus, in most cases, prevents buffering and provides smooth video watching experience. This option works with Youtube, Vevo, Hulu, Vimeo and so many other video streaming sites. Video Accelerator is especially useful when your ISP throttles single TCP sessions (like most Chinese ISPs do for International connections). We have disabled this option by default as for some users it might not work good.

6. Youtube Burst Mode – This option lets you stream Youtube in burst mode whenever possible thus avoiding excessive buffering

7. This option will keep connection with our server accross browser request. Normally you should keep this enabled for faster surfing speed. If you have a lot of tabs open in a web browser or a lot of tabs with facebook and you see frequently "Too Many Connections" error, try to disable this option.
