2.2.2 New Features and Changes¶

Security/Errata Notices¶

Added hidden config option to disable blocking of link-local IPv4 (169.254.0.0/16) for the rare instances where it’s required. Not recommended, violates RFC 3927.
Fixed invalid ruleset generation when using port forwards with destination “any” on a DHCP client WAN-type interface, have pure NAT mode reflection enabled, and have the interface with link up but unable to reach a DHCP server for an extended period. #4564
Allow the use of version IPv4+IPv6 on firewall rules without restrictions on protocol. The former restrictions date back to earlier base software versions, and are no longer applicable.
Omit route-to from rules specifying a specific gateway when that gateway is forced down. #4566
Use the subnet address when forming rules for networks, rather than the interface IP address
Added SCTP to the protocol drop-down for firewall rules

Enforce disabling of “prefer old SAs” option.Having this option enabled will cause connectivity problems after rekeying in many circumstances. Upgrading to 2.2.2 will fix this.
strongSwan upgraded to 5.3.0
Don’t apply mobile IPsec phase 2 PFS configuration to non-mobile IPsec. #4538
Correct applying of uniqueid configuration. #4359
Bring back automatic exclusion of LAN subnet to LAN IP for scenarios where remote IPsec overlaps with local LAN subnet. #4504
Enable ike_name for daemon logging, adding connection identifiers to IPsec logs that can be correlated to output of ‘ipsec statusall’ (GUI log viewer integration to come).

Fix DNS registration of hostname “0” #4573
Domain overrides to multiple server IPs are possible in DNS Resolver. Add message noting this, and how to achieve it. #4350
Always configure user-specified DNS servers in the Unbound configuration, to make its behavior consistent with dnsmasq
Only list nameservers once in resolv.conf

Atheros wireless driver updated to latest from FreeBSD 11-CURRENT. Not many changes since 2.2.1-RELEASE. #4582
Wireless cards removed from ALTQ-capable interfaces (traffic shaper capability) since that isn’t supported at the moment. #4406
New option “auto” added for Standard. This omits configuring mode with ifconfig, which currently can trigger driver problems that don’t exist when not specified. Standard “auto” is preferred, and possibly required, for BSS and IBSS wireless modes with Atheros cards (at a minimum, potentially others).

Make sure ‘DHCPv6 Prefix Delegation size’ is provided if ‘Send IPv6 prefix hint’ flag is checked to avoid generating invalid dhcp6c configuration file.
DHCPv6 Relay fixed. #4572
Allow “0” for id-assoc na ID, id-assoc pd ID, sla-id and sla-len DHCP6 configuration options. #4547
Fix the use of multiple prefixes in IPv6 router advertisements. #4468

Clean up logic in OpenVPN resync code. Discussion here and additional change here.
SSL certificate validation disabled for selfhost - their certificate chain had a problem that made OpenSSL fail verification, making the service non-functional. #4545 The provider fixed the issue after 2.2.2-RELEASE, so verification has been re-enabled for 2.2.3 and newer.
Fix error in traffic shaping wizard. #4529
Fix broken image path. #4530
A variety of minor text clean up in web interface.
Remove some code no longer used in a few places.
Clean up of code path when adding a new user. #4620
Make sure RRD backup is not restored when /var memory disk is not in use. #4531
Show friendly name of the interface on custom RRD graph drop-down selection
PHP upgraded to 5.5.23
Prevent a user from adding a VLAN using the invalid ID “0”
