2.4 New Features and Changes¶
Operating System / Architecture changes¶
Warning
32-bit support has been deprecated and removed – There are no images available for 32-bit (x86/i386) Intel architecture systems
Warning
NanoBSD has been deprecated and removed – There are no images available for NanoBSD, use a full install instead
Upgrade of base OS to FreeBSD 11.1-RELEASE-p1
Added support for Netgate ARM-based systems such as the SG-1000
Started using the FreeBSD installer instead of the old style installer (installation procedures have all changed)
The installer now supports UEFI #4044
If the new installer image will not boot on a specific piece of hardware, see Troubleshooting Boot Issues
The installer now supports ZFS
Added support to the new installer to copy an existing config.xml off an MS DOS formatted USB drive (formerly known as “PFI”) #7689
Added support to the new installer to optionally recover config.xml off an existing installation drive (works with UFS and ZFS) #7708
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
FreeBSD 11.1 includes MAP_GUARD protection to protect against attacks such as Stack Clash
A number of base system packages have been updated to address security issues, including dnsmasq, perl, cURL, and others.
Firmware Branch Behavior / Upgrading From Snapshots¶
To control how a firewall obtains updates, visit System > Update, Update Settings tab
Known Issues¶
Some systems may not be able to boot 2.4 installation images, for example, due to UEFI compatibility changes. These are primarily BIOS issues and not issues with the installer images. Upgrading from 2.3.x should still work on affected hardware.
Users with ESXi or VMware Workstation may experience a boot-time crash during hardware detection, due to a race condition in the FreeBSD VT console code. This crash is infrequent and does not affect most users or most boot attempts, but since it is a race condition it can manifest randomly. To avoid the crash, configure the VM to use the
sysconsconsole rather thanvtby editing/boot/loader.conf.localand adding this line:kern.vty=sc
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
Improved help text in various parts of the GUI
Wireless¶
FreeBSD 11 contains an updated 802.11 stack with numerous improvements
Warning
Wireless interfaces must be created on the Wireless tab under Interfaces > Assignments 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 conjunction 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
Fixed handling of Port Forwards so they do not make up new destination information when a configured against a DHCP interface that does not currently have an address
Fixed VLAN Priority pf syntax #7744
Fixed a problem where pf scrub did not properly re-fragment unusual but valid IPv6 fragments, resulting in overlapping fragments #7485
Fixed confirmation prompt handling when deleting a firewall state from diag_dump_states.php #7827
Changed display of 1:1 NAT rules to match other firewall pages #7728
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
Added upgrade code to work around broken shaper rules from older wizard code #7434
Fixed the Traffic Shaper so it shows interface names for disabled interfaces, rather than an ‘empty’ placeholder.
Fixed handling of the priority field for different ALTQ shaper types
OpenVPN¶
Upgraded OpenVPN to 2.4.x. #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 <https://redmine.pfsense.org/issues/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
Added locking to prevent issues with OpenVPN instance startup #6132
Check OpenVPN server/client option visibility changes per mode #7331 #7451
Added an OpenVPN GUI option for “fast-io” to clients and servers #7507
Added an OpenVPN GUI Option for “sndbuf” and “rcvbuf”, using the same value for both #7507
Removed references to the defunct OpenVPN client manager port #7568
Removed references to unused “Address Pool” setting in OpenVPN #7567
Fixed OpenVPN server port validation to disallow “0”, while still allowing it for a client port, which is the same meaning as blank/empty #7565
Fixed OpenVPN help text for route_no_exec #7575
Fixed description of the address assignment behavior for Tunnel Network fields in OpenVPN clients and servers #7573
Remove the GUI option for “resolv-retry infinite” from OpenVPN, it is always enabled #7572
Fixed the OpenVPN wizard so it better handles a user choosing a different type of authentication server than a previous run of the wizard #7569
Fixed OpenVPN Auth Digest Algorithm selection so it does not use duplicate/alias names in the list, and added upgrade code to fix existing entries on upgrade so they use the actual digest name and not an alias #7685
Fixed show/hide behavior of fields on vpn_openvpn_client.php in chrome #7451
Changed OpenVPN wizard certificate input validation and encoding so it matches the standards of the current certificate manager #7854
Fixed the OpenVPN wizard so it creates an OpenVPN server instance using current proper defaults #7864
IPsec¶
Upgraded strongSwan to version 5.6.0
Changed the default strongSwan logging levels such that IKE SA, IKE Child SA, and Configuration Backend all default to “Diag” #7007
Added an option to set the Rekey Margin for IPsec tunnels in the Phase 1 settings
Added RADIUS accounting support for mobile IPsec when accounting is enabled on the Authentication Server entry
Added checks to prevent simultaneous/repeated calling of vpn_ipsec_configure() by /etc/rc.newipsecdns
Added DH Groups 22, 23, 24 to IPsec Phase 2 selection for compatibility, but they should not normally be used for security reasons #6967
Certificate Management¶
Added a check to ensure that the public key of the Certificate matches its private key when importing Certificate Authority and Certificate entries to prevent mismatching keys from being imported #6953
Fixed error handling when creating a Certificate from the User Management section, failed actions will no longer fail silently #6953
Fixed handling of Certificates generated from an imported CA when no starting serial number was set #6952
Fixed handling of Certificate Authority deletion so that it does not remove associated certificates #6947

Added the ability for the certificate manager to sign a CSR using an internal CA #7383
Added the ability to set the certificate type and SAN attributes in a Certificate Signing Request #7527
Restructured how certificate types and SANs are handled in the cert manager when making a Cert/CSR/Signing, so each section can properly use the controls #7527 #7677
It is now possible to add SANs and EKUs to certificates when signing using the certificate manager
Note
Attributes such as SANs and KU/EKU cannot be copied from a CSR when signing due to a deficiency in OpenSSL’s x509 functions (they do not support “copy_extensions” at this time); These attributes must be specified manually when signing
Fixed “server” certificate detection to key off of the EKU For “TLS Web Server Authentication” since nsCertType has been deprecated
Added SAN, KU, and EKU information in an info block for each entry in the certificate list #7505
Added the ability to use a wider range of characters in certificate fields as laid out by RFC 4514 #7540
Added a useful error message when there is no private CA with which to create a new user certificate from within the user manager #7585
Fixed the User Manager so it adds the username as the first SAN when making a user certificate at the same time a user is created #7666
Added another possible Certificate Signing Request Armor string when validating on import #7383
