This release is still under development and this list of changes is a work in progress and subject to change.

Operating System / Architecture changes

  • Upgrade of base OS to FreeBSD 11.0-RELEASE-p?
  • Added support for the SG-1000 ARM-based system
  • 32-bit support has been deprecated and removed -- There are no images available for 32-bit (x86/i386) Intel architecture systems
  • NanoBSD has been deprecated and removed -- There are no images available for NanoBSD, use a full install instead
    • Work is in progress to investigate the possibility of upgrading 64-bit NanoBSD installs in-place to a full install
  • Started using the FreeBSD installer instead of the old style installer (installation procedures have all changed)
  • The installer now supports UEFI #4044
  • The installer now supports ZFS
  • Fixed issues with major version base upgrades via pkg
  • Changed cryptodev to load as a kernel module #5976

Security / Errata

  • Converted various parts of the GUI to use POST instead of GET when performing actions that change the firewall state (e.g. delete or enable/disable an item) to avoid potential issues with cross-site request forgery and unintentional repeating of actions #4083

Known Issues

The following issues are known regressions from previous versions that are still in progress:

  • Captive Portal is missing a mixed table with IP and MAC addresses, which means it cannot send MAC address as username to RADIUS
  • Captive Portal is missing statistics, so RADIUS accounting will not receive data

Cleanup

  • Misc code cleanup, removal of patches that were no longer necessary or were inefficient
  • Replaced multiple local copies of PHP PEAR libraries with updated copies using their official sources #3734
    • Notably, local static copies were replaced by their FreeBSD ports counterparts: pear, pear-XML_RPC2, pear-Net_IPv6, pear-Crypt_CHAP, pear-Mail, pear-Net_Growl
    • Code that relied on the old files was updated to use the current or replaced versions
  • Removed all references to GLXSB (it was 32-bit only) #6755
  • Removed all code in the builder and pfSense for handling the NanoBSD platform
  • Removed all calls to conf_mount_rw / conf_mount_ro, since they were only required for NanoBSD

Wireless

  • FreeBSD 11 contains an updated 802.11 stack with numerous improvements
  • Wireless interfaces must be created on the Wireless tab under Interfaces > (assign) before they can be assigned #6770

Firewall / Rules / NAT / Aliases

  • Fixed issues with synproxy rules on a WAN/LAN style bridge #6769
  • Fixed issues with limiters on rules that utilize NAT #4326
  • Fixed issues with limiters used in conjuction with a transparent proxy or other local redirect rule #7050
  • Fixed expansion of "Other" type VIP subnet entries in NAT destination drop-down selections #6094
  • Fixed NAT rules so that when a port forward is disabled, its associated firewall rule is also disabled #6472
  • Fixed handling of "URL Table (IPs)" and "URL (IPs)" when the file is hosted a server using HTTPS with a self-signed certificate #4766
  • Show firewall rule descriptions in a column when viewing the log on new installs, upgrades retain their existing setting #7323
  • Fixed firewall states showing a negative value for total bytes processed #7075

Traffic Shaping

  • Added extra warnings to traffic shaping pages when the firewall has no interfaces capable of using ALTQ shaping #7032
  • Fixed handling removal of shaping rules when deleting an interface #7231

OpenVPN

  • Upgraded OpenVPN to 2.4.0. #7054
    • This is a significant upgrade which includes support for a wide variety of new features, including AEAD ciphers such as AES-GCM.
    • AES-GCM can be accelerated by AES-NI, and is supported in SSL/TLS modes (not shared key) #7068
    • Added support for TLS Encryption as an optional TLS Key usage type. This encrypts the control channel, providing privacy and protocol obfuscation #7071
    • Added ECDH options to OpenVPN server and client options ("ECDH Only" choice for DH, ECDH Curve selection) #7063
    • Restructured the compression options to include LZ4 support and the new "compress" directive which replaces "comp-lzo" which has been deprecated. The old options remain for now, but are labeled "Legacy" #7064
    • Changed protocol selection for OpenVPN clients and servers because OpenVPN 2.4 treats "udp" and "tcp" as dual stack now #7062
      • Added "multihome" option in relevant protocol cases so OpenVPN will reply back using the address used to receive a packet #7062
    • Changed the DNS Server fields in the OpenVPN server options so they can define either IPv4 or IPv6 DNS servers to push to clients #7061
    • Added IPv6 support to status_openvpn.php and the OpenVPN widget #2766
    • Removed uses of the deprecated "tun-ipv6" OpenVPN directive, OpenVPN now always assumes IPv6 is enabled #7054
    • Replaced uses of the deprecated "client-cert-not-required" directive with its functional replacement "verify-client-cert none" #7073
    • Added support for Negotiable Crypto Parameters (NCP) to control automatic cipher selection between clients and servers #7072
    • NOTE: OpenVPN 2.4 handles CRL verification differently than previous versions, passing through validation to the library rather than handling it internally. This can cause some certificates to fail validation that may have passed previously. In particular, if a certificate is removed from a CRL, it may still fail validation until all copies of the CRL have been rewritten.
  • Improved the help text on OpenVPN Client-Specific Overrides #7053
  • Fixed issues with OpenVPN clients on dynamic or tunneled IPv6 interfaces (e.g. GIF) #6663
