[split] Chinese firewall

[RichardGv]

I don't quite know if this is able to bypass the great chinese firewall, but some years ago my ISP (Telenor) along with it's branches was judged to block all access to sites such as the pirate bay, mp3raid and such sites*. I never really used them, but i didn't like the fact that i was actually blocked from some sites. Therefore, I found out that i was able to change the DNS server to bypass the ISP firewalls. I also found that that i was able to bypass the school firewall with this method. I don't know whether this is able to bypass the chinese firewall, tho'.

Unfortunately, you generally cannot bypass our Great Firewall with the method: (It couldn't so "great" if it can easily be bypassed.)

1. The Great Firewall is known to search for DNS requests of the blocked domain, and generate a fake DNS response, with an inaccessible IP address returned. So regardless of which DNS server you are querying from China, if the request domain is blocked, you won't get the correct IP.
   
2. DNS poisoning is not the only filtering method. Aggressive IP block, URL filtering + TCP reset, etc., are pretty common, too.
