This update comes with a mix of new features and package updates. Please give it a good round of testing and report any problems back to the developers. If you would like to support us bringing you these updates and making IPFire the best firewall in the world, pleaseĀ  donate.

New Default Policy: Blocking Email Spammers

This release introduces a change in the default firewall policy for new installations: Blocking outgoing SMTP traffic from internal networks by default. We have recently seen that some installations have infected systems that send out large amounts of spam, resulting in unhappy consequences like having your firewall appear on blacklists and trouble logging into online banking.

We believe that this change that blocks any outgoing connections on port 25 (TCP) will stop this problem, as that port is only used for mailserver-to-mailserver communication. Client system will use Submission on port 578 or 465 instead and therefore this change should not cause any problems for almost all users, but block spam on the Internet. Existing installations won't see any changes.
