McAfee Gateway Blocking Internet Connection?

[cool_coder]

Hello,
I have a dell laptop since about a month. I have been using it to download various open source software's from my college through LAN ports. But since there is a McAfee Gateway limiting the download to 1GB. Hence i have been using freegate software for proxy server. Hence McAfee doesn't interfere with me. But since yesterday I have been unable to even connect to internet. There is a yellow exclamation on the monitor like icon in windows7 which says 'no internet access'. Freegate cant help me here because for it to work i first need internet access. However from the same port my friends are able to connect to internet.
Initially i thought that maybe this was a driver problem. But i installed the drivers again from the cd that i got with the laptop. Then i updated the driver. I am able to connect my laptop to broadband network in my home by LAN. I can also use WiFi from my smartphone's hotspot. However i am unable to connect through LAN in my college. My friends told me that the college authorities can block internet access to my laptop even though i use freegate. How is this possible? Can anybody please provide me with a solution? I am really frustrated!

If this mcafee gateway is in between you and the internet I am unsure how the freegate software could get past a bandwidth limit. Most the time it is used to bypass site restrictions.

If we assume you are actually getting a IP address and they are blocking it have you tried to set a different ip. You could try to change the mac address on your machine and see if you get a different ip.

Now none of this will work if they are smart and require you to log into something before granting access. This ties your IP to a user which then lets them limit you no matter what IP you happen to use....if they are stupid then it is trivial to bypass

thanks for replying.
normally anyone wanting to use internet needs to enter their pid no & a password. then mcafee restricts some sites & monitors data usage. but since we all use freegate mcafee doesnt know that we are using internet from our college server due to the 'proxy server' provided by freegate.

how do i change the ip? how do i change the mac address? sorry but i am not a comp guy, thats why...

as i said before, after launching freegate we dont need to provide our pid, password, etc.

any solution?

They may not know exactly where you are going but they do know how bytes you are transferring. If they are blocking due to byte count they will just see the traffic going to the freegate proxy server. If bandwidth is the main concern they may not really care you have 1g to go to the proxy or 1g to go to some other site. The main use of vpn/proxy is to bypass site restriction. Ie no porn or whatever. Many of the filters block these VPN sites. I know the filters I use at work blocks almost every VPN site because it is a know way to bypass the filters.

Because they require a ID they can block traffic based on this id. They will take the ip address of machine you logged in with and apply the rules to that ID. They of course block traffic by IP address but they dynamically apply rules to this IP based on the profile for your ID.

Both options are changed in the network settings for the connection you are using. The IP is changed in the TCP setting and the mac is changed under the physical adapter for the nic card. The mac setting is called network address in advanced tab on many devices.

I suspect you are stuck and going to have to call them and ask if you have been restricted and what you need to do to regain access.
