From: Wulf Solter on 12 Apr 2006 07:57 Hiya. A computer im doing some work on has an Internet connection (company provided) that blocks port 80 (Definitely ISP blocking port 80) . The need has come up to access hotmail (login page is HTTP), and i can't figure out a way to bypass the block. Anyone with some brilliant suggestions or clues? Much thanks in advance, wulf

It is the ISP that only allows certain ports through (HTTPS, SMTP/POP3, FTP, etc..) Not really to keen on getting another net connection at $x just for webmail.

I've heard of people running sshd on a box at home, and if outbound port 22 (or whatever port they run sshd on) is open, they do an ssh connection with X forwarding, and run the browser on the remote machine that displays on their local machine behind the block. All encrypted data pass though port 22 outbound, and the port 80 connection is done from their home machine where it's unrestricted.

If I understand correctly, this ISP is blocking its clients from connecting to servers on port 80 on the Internet? That's...very bizarre. It's far more likely that your company's IT department is doing this blocking. Perhaps someone complained to them about the number of hours being wasted "surfing" the web. Or there could be semantic games afoot. Perhaps your company requested that the ISP put the block in place for the aforementioned "wasted hours" reason. That would make it true that the ISP is blocking, but would also explain why the ISP would take so odd an action. Have you tried asking the ISP? - Andrew |
