PeerBlock lets you control who your computer "talks to" on the Internet. By selecting appropriate lists of "known bad" computers, you can block communication with advertising or spyware oriented servers, computers monitoring your p2p activities, computers which have been "hacked", even entire countries! PeerBlock blocks "known bad" computers from accessing yours, and vice versa.
Depending on the lists you have it set up to use, you can block governments, corporations, machines flagged for anti-p2p activites, even entire countries! Whether youre sharing files with Bittorrent or just surfing the web, PeerBlock can help protect you from the bad guys. They cant get in to your computer, and your computer wont try to send them anything either.
PeerBlock monitors each connection your computer tries to make with another one - and each connection other computers try to make with you - and then compares the other computers IP address against a list of "known bad" IP addresses to see whether it should let this connection go through or not.
Whats new in this version:
- Port Allow List - The new "Port Settings" tab allows you to unblock ports (incoming and/or outgoing). This means that PeerBlock will not filter any connections from/to those ports. This can for example be used if youre running PeerBlock on a public FTP server, or if you want to ensure that outgoing SMTP mail communications are never blocked.
- First-run Update Message - When you first run PeerBlock after upgrading, you will see a notice explaining why lists are only updating once per week. Hopefully this will help to alleviate peoples confusion about this.
- Better Weekly List-Updating - Weve made some improvements that should help ensure that free users continue to get their free weekly list-updates.
- I-Blocklist Subscription Settings - To make it easier for you to configure PeerBlock to use an I-Blocklist Subscription, new I-Blocklist Username/PIN fields have been added to the bottom of the "Settings 1" tab.
- Separate Settings Tabs - Instead of having one Settings tab with those silly "Next" and "Prev" buttons on it, weve broken that out into two separate "Settings 1" and "Settings 2" tabs.
- Improved List-Update Error Handling - Weve worked with I-Blocklist, who hosts the vast majority of the lists people use, to create improved error messaging for the various problems that may occur when updating lists. If something occurs during update-checking, the error message displayed should be much more meaningful.
- Improved List-update Error Window - Should you hit any errors while updating your lists - 429 or otherwise - we will now pop up a more informative error window, along with a button you can click to jump straight to our site to check for more information.
- Updated Error Windows - If you encounter a catastrophic error, the message that appears will now tell you to go visit peerblock.com/errors. This will redirect you to a forum-post on which the most common error-messages are displayed, to help you figure out what has gone wrong, and what can be done to fix it.
- (Re)Load Previously Downloaded Lists - Previously, there was a problem where if you disabled and then re-enabled a list in the List Manager, that list wouldnt be reloaded until it successfully downloaded an update. Now, if it cant update that list it will still load the last version you did successfully download.
- Removal of Windows 2000 Support - Windows 2000 is quite old by now, we hope that nobodys still running it; if you are, you can continue using the previous PeerBlock version. This release does support all Windows variants from Windows XP through to Windows 8.1, including server variants. (But not Windows RT.)
