How to encrypt internet traffic on port 80?

16 posts in this topic

Hello Guys!

Our ISP administrator suddenly changed the way we connect to internet, from LAN to PPPoE connection, and this last one is very slow, like 10-12KB/s. On LAN connection, I was downloading at 500KB/s.

After PPPoE connection was implemented, I discovered a method to use the old and fast connection: using a ssl web proxy, like this:

https://www.circumsurf.com/

After a while, the network administrator was probably alerted by the amount of data transferred through the LAN connection(I was downloading up to 2-3 GB/day, maybe more) and he had probably decided to close the port 443 (ssl) and redirect all connection from LAN to an intranet https login page.

Now, I know that the only allowed connection is the http on port 80.

My network knowledge is pretty poor, so who can help me and tell how to establish a crypted or secure connection on port 80 as to overpass the intranet redirection page and to access the web?

Do you know any gui or simple application that would do that?

Thank you for any help!

So port 80 is open but any attempt to use it redirects you to a login page?

I don't know much about SSH, but you should maybe check it out.

p.s- Thank you for being new and not asking how to do something completely skiddyish.

Yeah, it redirects me to a login page, everytime I want to access any site. When I was using the ssl connection to the secure web proxy, this redirection was impossible, because the traffic was encrypted. But as they close port 443 (SSL), the onlly open port is 80 and unless I encrypt the web trafic, it redirects me.

I tried to connect to https site like this:

https://www.circumsurf.com:80

and it does connect to the remote site, but the page is not loading, because the ongoing traffic is on port 443 which is closed.

I have openssh and putty but I think I need a shell account, I mean a remote server to connect to before I connect to internet.

Well yeah, I was assuming you had one.

If it's a remote shell you're looking for, then I can recommend this one : rootshell.be

A 24x7 SSH connection to a UNIX host connected on the Internet

See what they offer, maybe it works. They don't allow proxies though.

Thanks! I'll see what I can do.

I found THIS in their forum, might be interesting :)

i'm not an expert on networking either, but here's a list of ports: http://en.wikipedia.org/wiki/List_of_TCP_a...DP_port_numbers

you can use a port scanner to see which ones are open on your network. so yeah, ssl uses 443, so that should be closed. ssh uses 22. but yeah, you'd need a shell account somewhere to use that as a proxy.

if you want an encrypted connection but don't mind things being slow, you can use tor, which i'm pretty sure goes on port 80 with everything else. it encrypts your connection all the way up until the last node.

You say you are redirected to a login, do you mean if it uses anyother port than port 80 ?.

My problem is , its just too easy to say go here and uses this or down load this. if you want to learn to hack, your best bet would be to learn how it works and code it yourself.

Thank you all for your help! The login page is a https page, and it is redirecting any site request. For example, if I want to access

http://www.binrev.com/forums/

it starts loading the page but then the connection is redirected to that intranet login page.

That login page is something like this:

https://gateway.site.domain:8001

I assume that port 80 is still open because my browser starts loading any site, except for https, but then the login page appears.

I think is a good idea to use a port scanner to see what ports are open, I will try to find one.

Another think that makes me believe that port 80 is still open is when a I enter any https site like this:

https://www.circumsurf.com:80

it does connect to that site but it fails loading as incoming connection to 443 port are restricted.

I have Torpark_2.0.0.3a but it can't connect to any site.

Personally I would call your ISP. Complain to them. If that does not work, switch ISP's. Telling them you are going to be taking your dollars elsewhere can solve a lot of problems.

just change the ssl listen to 80 or just run sshd also may want to use IP if they have DNS blocked etc ... with firefix you can tunnel DNS also ;)
