hi,

My PC is connected to LAN and we use a proxy for internet access. The admin has a firewall so we cant browse some stuff.
recently i come across this software JAP and FREEDOM and using these to softwares i can browse anything.

for example when i type CHAT in GOOGLE i used to get ACCESS DENIED but now if i run FREEDOM and change my proxy to LOCALHOST:8080 (this is the port that freedom runs on) i am able to successfully get what i want.

i even can use YAHOO MESSENGER and all other chat engines which was earlier disabled.

i was reading few articles about ANONYMIZATION and found that i use a different server or something like that to access a site but what i couldn't understand is first of all how come i am able to send this data to freedom server when my firewall blocks those packets which contain KEYWORDS like chat etc.. because freedom first of all is connected by my proxy server

pleas suggest me some link where i could learn how these anonymization work or more appropriately how these softwares are able to cheat our own firewall (i know few basics but i am looking for some advanced stuff)

hoping you could help me.

PS: if i am vague in specifying my problem please let me know so that i could add few more details if possible. i added this coz i havent got replies for many of my posts and thought i am not specifying my problem correctly.

Very simply the software you cited uses a low level encryption system on the data packets sent from your
computer. The company's software/firewall does not block this data as it doesn't recognized any keywords
in that encrypted packet.

Additionally you're sending to a static IP address server to start. Apparently the company's software
doesn't block this IP.

The same procedure in reverse allows the information to return past the company's software and firewall.

This link explains a bit about the anonymization process and "onion routers."

A search using Google will show similar information from many sources.

Hope this helps you.

thnks a lot that helped. i had also googled and found few intresting topics. thnk u again

just another thing. recently i freedom servers have been blocked in our lan and when used NTLM APS i was able to run freedom again. i think NTLM APS has got nothing to do with encryption but it just makes the server believe its taking with the browser what does this exactlyt mean??
