Free Anonymizer for interactive content

[SatStorm]

Hi,
my company changed server and now the internet trafic is logged and monitored (in my country this is legal - illegal is someone turn on your PC and search it).

Since then, some sites / servers I use to visit blocked and now I'm not able to access them direct.

I bypassed this problem for now, by using various online anonymizers.

The problem I have, is that on various forums, I need to log in so to read the content. I'm not able to do this, 'cause I don't know any free web base anonymizer offering this (they are all pay services).

Let me explain: I'm not care to "hide" myself online. Just to bypass the traffic control / andress block, my company's server has put on us. So, it doesn't have to be an anonymizer! Just an online service that I could log in and use it as a virtual browser of mine, just to baypass the limitations I'm now facing on browsing pages.
I don't care to download stuff from those sites, just to log in and browse them!

From what I know, our new server is Linux based. It's a black box without even a monitor (our older server was windows NT - that was easy to bypass...). It is controlled by someone online (he don't even have to come here to "check" it) and rarelly reports to our boss.

My PC runs win2K and any advise regarding this would be appreciated. I mostly need something freeware (of course), but if that is not possible, point me other alternatives

Thanks in advance!

Thanks for the fast email replies!
I installed "Jap" which - for now - bypass those limitations I facing! Not bad, not bad! Any other web based alternatives?

Thanks!
