Firewall bypass?
24. August 2008 - 2:32
note: this topic is not meant to be read/commented in by people who think they have to obey all laws and standards. It was never stated that I was not allowed to by-pass the university's firewall. I was never even told they blocked anything when signing the dorm agreement.
alright i moved to my university and they have blocked just about every port possible in the firewall. Does anyone know a way around? Would I be able to convert all the data locally and go through port 80 for q3, torrents, etc?
Is there a reliable yet cheap (hopefully free! but i doubt it) TCP tunnelling or something similar? I would prefer to not go through a proxy but.. anything is worth a shot i suppose
Basically I would like to get around the firewall without having to pay money for extra bandwidth. All suggestions and solutions will be greatly appreciated.

You're sort of leaving us out of the blue... are you using wifi, or local area (modem connected somewhere), and what specifically are they using to block your access? does it pop up as a warning or is it just inaccessible

Yo Joey. Had EXACTLY the same problem when i went to my Uni 2 years ago.
No way to unblock/ tunnel it unless you're really friendly with the campus IT Maintenance department. If you're really good at people relations, that means a quick chat and a lie like "i need it for 2 months to test my thesis which is due in April " or "i need ports 5000-70000 for my project in internet bypass blablabla"... or slyly (right term for the word "sly"?) attempt to grease they paw... everyone likes that (just make sure you do it in innuendos).
Cos otherwise (if tunnelling DOES work which i doubt will be an easy solution.. and might have many vices), your socket might get temporarily or permanently swtiched off depending on circumstances and your "usage of the Campus internet service" contract you signed.
Regards,
Shady

You could use Teamviewer, a free VNC software which uses the outgoing Port 80 (HTTP), to at least reach an outside connection...the outside connection you don't have. I don't see any other possibility.
Are you sure that it's a firewall which blocks you? If you are lucky it's just a Proxy filtering via blacklist/whitelist which means you could use Tor.

yeah i practically sucked his dick and no go
I am pretty sure
I tried tor for about an hour, no go.
Maybe I do not know how to use it correctly.
I put q3/utorrent through sock caps (socks5/4) on listening port 9050/9051 and there was absolutely no data flow. I am thinking that just means I am not setting something up correctly. I will have to look again later. I do believe I tried something similar earlier.
Yourfreedom is costly. Ill check out the free package later i suppose.

Sub could Teamviewer bypass a hardware firewall? And if its possible can they detect it? Seems that we have one at work with all incoming ports blocked.

Jep, it can bypass firewalls since it looks like a plain HTTP request for many of them. I doubt that your admins are that clever/professional that they have application filters in use which means that every program/application has to register itself via its signature on the firewall.
I'm not sure if it can be detected, but I doubt it, since it's encrypted. But maybe just give it a try, install Wireshark and analyze the traffic. Watch out for port 5900 which is Teamviewers TCP/IP data port (encapsulated in HTTP with 'DynGate' (<-Routingserver)).
To carry it to the extremes, you could even tunnel TCP/IP itself. Means your tunnel is not based on the application layer anymore but on the transport layer (OSI layer 4). I'd like to advise you to use Open Secure Shell (SSH) to realize this.
But: It's not that easy. No stylish GUI, no easy clicking. You have to be a very technical user to deal with this.

Well its a government body,this is in no way an argument to defend the admins that work there,or their level of knowledge hehe, but it might be serious. Altho i broke the admin codes (bypassed) on 2 pc's there...ups,i better say no more 
Lets just say a mate and me are on probably the only 2 pcs out of 100 or more on which u can actually install software and have full access [...] Sadly firewall is blocking us from full power,10 MBit conn going to waste on http browsing [...]

Majority of your post was a bit too complex so i quoted the only parts which i understood 
Seems I have struck a golden nerve with this question - your field of expertise obviously so maybe u can explain the whats and hows a bit better in irc or msn 
And try to simplify pls...one step at a time

uh all you need to know is it is there is a firewall blocking me
how i get to the firewall is of no importance
Everything runs on the same network. Meaning it's wired and wireless accessible. Because it is the same network it runs on the same firewall. Obviously the connections time out because the access is blocked meaning there is no warning.
it is very standard for a university to do this so, it is similiar to many universities in the US. They simply block all ports except for the standard web surfing ports.
I am simply asking if there is a simple/fairly easy yet cheapish way to get past this. I am also asking would it be possible to convert all the data (like q3, torrents, etc) and send through port 80 instead of the client's standard port.
I know tunneling can be a solution however it costs an arm and a leg to do this. I also do not have access to a stable outside connection to set this up. Does anyone know of a cheap/free service that could suffice? I am open to all ideas.
I may be asking a little too much of the e+ forums but I figured it was worth a try.
Thanks.
