firewall help

Ok I'm completely new to this, I attend a university and live off campus in an apartment complex with a T1 connection supplied by the complex.

They have blocked all ports that I can tell, and I checked that website that checks to see if you have any ports open and they all came up stealth.

No Gnutella based applications work. I've read a lot of things suggesting that I just change the port, but I don't know of any I have available to change to.

I tried reading up on Httport and using proxy (tried toadnode and Winx) with no luck. I was able to search with Winx but I wasn't able to connect to download anything from anybody.

Any help would be great... thanks
 
I might be able to help (I am familer with firewalls but no expert).

You probaly have a transparent firewall. The firewall is up to block incoming requests. Which means that you can connect to other people and send them requests but they cannot send you a request. They can however reply to requests you make (i.e. You must initiate the connection)

So, what this means is that you can only download from people who do not have a firewall (there are lots of users out there without firewalls).

An easy test:

1) Launch you gnutella client
2) Do a search for something that will have huge numbers of hits (like 'madonna')
3) Pick whatever file has the most hosts and start downloading it (*Note: I am assuming here that whateve client you use will try all the different hosts)

If you eventually get a file to connect, then you know that you can connect with people who are not behind firewalls (unfortunatly the number of people without a firewall gets smaller and smaller each day) you simply won't be able to download from other people behind firewalls.

If you cannot get any downloads to work then the firewall may also block most outgoing ports. You may be able to change to an outgoing port that is not blocked... go to this link where it will give you the port assignments for many common applications. Pick something like AOL instant messanger and see if that program will work through the firewall (i.e. Install AIM and see if it works). If it does, then you could use that port with your gnutella client (Of course, you would NOT be able to use AIM at the same time)

Good Luck
 
If you get any search results at all I think it is surefire that you can download files.

To conduct your port scan properly, you should run up the client and pick a port first, otherwise the port will not be seen as open.

Here is an interesting article which will show you the problem from a sysadmin's point of view:
