My college uses the SonicWall firewall to block websites and unauthorized internet connections. I installed Tor 2 months ago and it worked fine. However, I'm trying to connect to the Tor Network (when I open Tor Browser in the TB folder) now and it doesn't connect. Here's the log file generated after the error says that Tor failed to establish a connection. Can someone help me in establishing a successful connection using Tor?

EDIT: Steps I am employing.

  1. I have to log in to my SonicWall firewall using a UserName and Password. Without doing this, internet connections aren't successful.

  2. After logging in and gaining internet access, I start the Tor Browser.

  3. The first Question: No, I don't need a proxy to connect to the Internet. My network connection is firewalled I think because whenever I try to open a website before logging in to SonicWall, I'm redirected to a login page first.

  4. The second Question: Although my computer does go through a firewall, after logging in, I can use the Internet except a few sites which are blocked. HTTP, HTTPS work fine on both Chrome and Firefox.

  5. Third Question: I don't know whether my ISP blocks Tor connections. When I select no, the connection window doesn't even open. When I click Yes and try to use bridges, none of them are successful.

U need to login in your browser!? I think you have a proxy web server there! If its true, try set Outbound Proxy in torrc file.

c torManual page: https://www.torproject.org/docs/tor-manual.html.en#HTTPProxy

In most censorship cases, the Pluggable Transport will work. You can try that and test your luck. However, remember that it is possible that you maybe uncovered. Think about that and decide the prudent action.
