Now, any good Network Admin thinking about security would have these blocked, but what we have done is told Hamachi to use Port 80 for inbound and outbound traffic, thus meaning that it sends all the data through a port normally only used for HTTP traffic which is the exact same traffic that the firewall would be letting through so the internet will work. Hamachi, in its normal flavor uses the following ports: Much easier to enter a string of "Why this should work: That is the thing, you can only block a website by name, not IP, as you can never be sure the same IP will be visited again and again, after all, Google has a few thousand IP Addresses, so if you wanted to block Google by IP, you would need to enter a few thousand addresses into a database. "Do any of you know the IP of " and one of them, because it is outside the schools firewall, will say "Yes, it is x.x.x.x" and your Web browser will then navigate to the IP Address, which is not blocked, and load the website.

This is where most people have problems, but wait, your PC has another network, so instead, it will ask the Other Computers on the network: Now, the way that DNS works is that if your school has the filter in, what will happen is that your PC will ask the school "Do you know the IP of " Thsi will flush your DNS resolver cache, now, make sure that your laptop can see the server and connect with it, ping should do that, so ping the address of the Server, not the Internet Address of your router or the internal network address, but the 5.x.x.x/8 address that your server will have in its console. In teh command prompt type: "ipconfig / flushdns"

Now, go to your laptop that you take to school (Assuming your school lets you use your own lappie, if they give you one chances are you can't install anything on it so you've just wasted your time) and install Hamachi.Ĭhange the ports on your Laptop to port 80.
(I assume I don't have to mention you have to install Hamachi first.) Set it up so that both TCP and UDP are using Port 80 (Settings->Preferences->Status->Detailed Configuration) Then set yourself up a server as per-normal. Set up the Hamachi Client at home, on a computer that will be always on and connected to the internet, or at a friends place, it doesn't really matter. When it detects that your PC is searching for, let's say ( I have yet to find a school that hasn't banned 4Chan) the DNS Server will redirect the request for a webpage to either nothing (Browser returns a 404 message) or to a custom page saying "Access Denied - You have been blocked"
This in effect is quite simple, when you access a schools wireless network using your own laptop, you are placed into a Virtual Local A rea Network within the school's IT System, this system runs through a DNS Server or, a Proxy Server, I've seen both setups, which filters the strings that your PC is searching for. Okay, well, if you want more information.

If your security policy requires you to specify explicit domain or IP ranges, then configure your firewall exceptions for outbound TCP ports 8200, 443, and 80 as well as UDP ports 82 for the GoTo domains or IP ranges, including those of our third-party provider networks.Actually, I was prepared to write up a whole article on how to do this. To address this problem, verify that the domains or IP ranges will not be scanned or filtered by specifying exception domains or IP ranges.
If your firewall includes a content or application data scanning filter, this may cause a block or latency, which would be indicated in the log files for the filter. Maintenance and failover events within our infrastructure may cause you to connect to servers within any of the ranges. These changes are necessary to continue to provide the maximum performance for our GoTo products. Use of IP ranges instead of domain names for the firewall configuration is discouraged unless absolutely necessary because our IP ranges and those of our provider networks need to be periodically audited and modified, creating additional maintenance for your network. Also, the client-to-host connection uses peer-to-peer connections, encrypted within an HTTPS tunnel where data is encrypted with AES-256 symmetric cipher. It is recommended to use wildcard rules whenever possible while allowlisting or blocking any GoTo services on your network as sub-domains of the domains listed above are included.
