| __TOC__
| |
| To access Second Life from inside a closed network, such as at an academic institution or corporate office, you may need to configure Second Life to route its traffic through designated [http://en.wikipedia.org/wiki/Proxy_server proxy servers]. Proxy servers allow Second Life to communicate with critical resources outside a closed network.
| |
| | |
| {{KBnote|Many schools and companies maintain proxy servers specifically for this purpose; if you need to connect to Second Life through a proxy server, contact your network administrator for the addresses, port numbers, and necessary credentials to complete the instructions below.}}

| |
| Second Life allows you to configure two types of proxy servers in order to route three distinct types of traffic necessary for connecting to and properly experiencing Second Life.
| |
| | |
| To access the Proxy Settings window:
| |
| # Choose '''Me > Preferences''' from the top menu bar.
| |
| # Click the '''Setup''' tab of the PREFERENCES window.
| |
| # Click the '''Adjust proxy settings''' button to open the Proxy Settings window.

| === HTTP proxy for web pages ===
| |
| The HTTP proxy for web pages is specifically for routing HTTP traffic meant to be viewed inworld via the [[Viewerhelp:Media_Browser|Media Browser]] or [http://community.secondlife.com/t5/English-Knowledge-Base/Shared-Media/ta-p/700145 Shared Media]. It is not necessary to set up this proxy in order to connect to Second Life from inside a closed network, but you will not have access to web content.
| |
| | |
| To configure an HTTP proxy for web pages in the Proxy Settings window:
| |
| # Check '''Use HTTP Proxy for Web pages'''
| |
| # Enter the HTTP proxy's network address and port number in the '''HTTP Proxy:''' and '''Port number:''' fields, respectively.
| |
| | |
| === SOCKS 5 proxy for UDP traffic ===
| |
| The SOCKS proxy is responsible for routing UDP traffic (and potentially "other" HTTP traffic; see below) between Second Life and resources outside your closed network. If you are on a closed network, such as at a school or corporate office, you must configure a SOCKS proxy in order to connect to Second Life.
| |
| | |
| To configure a SOCKS 5 proxy for UDP traffic in the Proxy Settings window:
| |
| # Check '''Use SOCKS 5 Proxy for UDP traffic'''
| |
| # Enter the SOCKS 5 proxy's network address and port number in the '''SOCKS 5 Proxy:''' and '''Port number:''' fields, respectively.
| |
| # If your SOCKS proxy does not require authentication, you're done!
| |
| #* If your SOCKS proxy does require authentication, choose the '''Username/Password''' radio button under SOCKS Authentication and enter your user name and password in the marked fields.
| |
| | |
| === Other HTTP traffic ===
| |
| In addition to web and UDP traffic, Second Life uses HTTP for a few other purposes, such as loading textures on objects. You may choose to route this "other" HTTP traffic through ''either'' an HTTP proxy or SOCKS 5 proxy. If you have configured both, consult your network administrator to determine which proxy server will provide you and your network infrastructure with the best overall performance.
| |
| | |
| To select a proxy for other HTTP traffic, choose from one of the available radio buttons under '''Other HTTP traffic proxy''' in the Proxy Settings window. You cannot select a proxy you have not yet configured.
| |
| | |
| == Caveats ==
| |
| Certain features do not work properly when you connect to Second Life using a proxy server:
| |
| * Voice chat does not work.
| |
| * The automatic updater does not work.
| |
| * The crash logger does not work.
