16.0

Overview
16.0.1 is a major release containing the new WireGuard VPN application, UEFI support, and many improvements and bug fixes. There was a minor package change in early 16.0.1 testing which created 16.0.1 release. Previous 15.1.x releases will upgrade directly to 16.0.1.

WireGuard
WireGuard is a very simple, yet fast and modern VPN technology that uses state-of-the-art cryptography. It can be used in both site-to-site environments as well as mobile devices. Learn more about the WireGuard App in the WireGuard VPN wiki page

UEFI
You can now install NG Firewall on UEFI for most modern BIOS platforms.

IPsec

Failover
If you use WAN Failover, you can now specify to use any "Active WAN". When the primary WAN switches, IPsec tunnels reconnect using the new link. On the remote endpoint, there is a new option to allow the incoming tunnel connection from any address.

Better performance
IPsec now uses AES-GCM as the default cipher resulting in a significant performance boost.

Improved reliability
The mechanism to detect the tunnel status has been improved, resulting in better reliability of IPsec tunnels.

Remote GUI over IPsec tunnel
Added the ability to access the remote NGFW over the IPsec tunnel.

General VPN Improvements
Tunnel Persistence
Active OpenVPN and IPsec tunnels are not affected by configuration changes such as adding a new tunnel.

Automatic LAN configuration
If you change the IP address of a LAN interface, this change will propagate to WireGuard, OpenVPN, and IPsec tunnels.

Threat Prevention
Threat lookup
The Threat Lookup tool now shows the results from both "client" and "server" reputation values. Prior to this release, the lookup returned only the server reputation.

Custom block actions
You can now redirect the user to an external block page URL or you can choose to block the connection without redirecting the user to a block page.

Pass Sites
You can now create exceptions for IP addresses and URLs without having to create individual rules for each item.

Other
Numerous performance improvements have been made to reporting and HTTP traffic processing.
Admin UI now operates on applicable interface aliases.
SSL Inspector now supports TLS 1.3.
Under Config, System, the new Logs tab allows you to better control disk space used by logs by specifying retention.
Report retention can now be configured at an hourly resolution.
Event reports can now export what is displayed or the entire table.
Web event reports now have the host field before the URI field.
Remote syslog events are no longer cut off at a certain size limit.
Disk space now uses a more accurate calucation.
Exporting JSON content columns issues has been fixed.
L2TP local directory auth fails after deleting IPsec tunnels has been fixed.
Removing remote server from OpenVPN does not close connection has been fixed.
Better error messaging on OSPF configuration issues.
Policy Manager rules race condition on upgrade fixed.
Parse large log directories correctly.
Upload root certificate.
Enforcement of strong cryptography SHA-512 for credentials
System Requirements and Technical Notes
32 bit upgrades will no longer be provided from 16.1 onwards
The software appliance installer for USB disks now uses the ISO file format, the same as for CD media. Therefore, as of 16.0 the IMG file download is no longer necessary and removed from the download page.
The WireGuard app is not available for cloud deployments (Amazon Web Services or Microsoft Azure). AWS and Azure deployments will update to version 16.0.1 if automatic updates are on, but the WireGuard app will not be included in that update.
Ports 80 and 443 are now reserved on all IP Addresses, including aliases. This means that port forwarding on TCP ports 80 and 443 are not functional unless the services are moved to alternate ports. Additional considerations regarding service ports are described in the Knowledge Base article What happens when I change my service ports?

 

15.1

Overview
15.1 replaces the underlying Debian Operating System from Stretch to Buster (Debian 10). This includes a new kernel 4.19 also.

Upgrading to version 15.1 requires a reboot to the appliance. Additionally, the database is reindexed which can take around an hour. Whilst the database is reindexing, NG Firewall is online and working but the main dashboard UI will not update during this time.

15.1 does not come with a 32 bit installer. 32 bit deployments, however, are still supported.

Upgrades are available for 32 bit deployments. 32 bit 15.0 deployments can be upgraded to 15.1
32 bit backups can be used on 64 bit installs
The OpenVPN client for Windows is no longer included. Current installed and configured clients will continue to work. OpenVPN clients are available for Microsoft Windows and Mac OS from OpenVPN which can be used with NG Firewall 15.1. See our OpenVPN documentation for more details.

Note also that most VPN clients no longer support MD5, including the official OpenVPN Windows client as it was found to be a severely compromised security technology a few years ago. Whilst NG Firewall had a temporary workaround to allow administrators the time to update their MD5 certificates, this is no longer supported in 15.1. For deployments that are still using MD5 certificates, administrators will need to uninstall and reinstall the OpenVPN app, and distribute the new OpenVPN configuration to VPN clients.

Features
New 'Close Session' option for Web Filter block pages
Configuration backup to Google Drive does not require Directory Connector anymore
Bug Fixes
Fix: Webfilter categories get reset after a restart
Fix: DHCP relay fixed in dnsmasq 2.80-1
Other Changes
Removed Root Certificate Installer (Windows) from SSL Inspector. To install the root certificate, go to http://your_server/cert to download and install the root certificate. More details in SSL_Inspector
