Ok at school we have internet, but these guys just block the internet.. all we can access is the intranet. The strange thing is that we can ping all websites we want.. but if we open FF or IE it displays an error as if there was no internet (Like server not found in FF, and page cannot be displayed in IE)

So how come we can ping? Is there a way to 'exploit' the ping thing and instead browse the actual webpage? Any programs that might overcome this problem?

Thanks.

A ping is a ICMP packet, most likely they aren't bothering to filter it.

Well, today they modified some privileges.. and now all we see it a one-way sign and says ISABouncer... all we can access is the intranet.. BUT my school is split into 2 buildings and has 1 wireless network... the strange thing is that from one building I can access internet normally, and from the other building I can't. I mean it's 1 wireless network... how can this be possible?

Very strange... perhaps it's two wireless subnetworks, each operating slightly differently.

What do you mean?

BTW we have a login name and a password, not just a simple WEP key, and each user can be restricted from somethings.. for example the Admins can set my acc to have internet and can block internet to my friends... well idk if this can be of any help... just saying.

I thought maybe there's a new wireless network for the new building, but it uses the same internet connection. Or, it could just be new routers installed. Even though the network is the same, each router could have its own privilege settings.

Yeah, in fact. They have one wireless router in one building, then in the other building there is another router that connects to the other and this router supplies internet in the second building... but how come our teachers do have internet... while we don't? I mean for sure the router is not blocking port 80 or something.... because if it did... neither our teachers would have internet.

It could be a user privilege setting that blocks non-admins from leaving the local network. Windows Server has various settings that may be involved.

We've got lots of restrictions at school:

@ 50Mb storage space limit
@ No Task Manager
@ No settings changed other than mouse options
@ No saving files on desktop
@ No doing anything interesting

See the problem?

Well we don't have that much.. everyone can have his own documents etc... But the internet... :(

BTW.. if it was a user privilege why would we have internet in one building and not in the other? If it's the same network.

Maybe they haven't got round to configuring the router. Ask your teachers?
