2.3.3 New Features and Changes

Security / Errata

Known Issues

  • The Captive Portal Disconnect All Users button does not fully disconnect all users PR#3565
  • RFC 2136 Dynamic DNS Entries will show red on the Dashboard widget even when correctly updated #7290
  • If an OpenVPN server set for SSL/TLS+User Auth contains a single user certificate shared between multiple users with different usernames, the Duplicate Connections option must be enabled on the server. In this situation, each user must have their own unique certificate or the certificate requirement should be removed (User Auth only). As this configuration is not valid nor a recommended practice, this issue is not considered a bug. When this condition is present only a single user can connect, additional users may see a client log entry such as “CreateIpForwardEntry: The object already exists”.
  • Firewall rules without an IP protocol set in the configuration which also have an ICMP type set may not load or display correctly. #7299 #7300
