Jump to: navigation, search

Overview

9.3 contains many platform and application improvements. It also has infrastructural changes to simplify settings and improve performance.

User Interface

  • Upgraded to ExtJS 4.1 (from ExtJS 2.2)
  • Added Session graphs to faceplates
  • Added more metrics to faceplate metrics list
  • Improved session viewer with filtering, grouping, and additional fields
  • Removed "Block page" skin settings - it now uses the main skin setting.

Policy Manager

  • New UI.
  • Policy Manager rules now use rulebuilder.

OpenVPN

  • Full tunnel now supported. Simply enable "Full Tunnel" in the address pool of the clients/sites you wish to use full tunnel mode.
  • You can now export any and all IPs (including WAN IPs)
  • "Full tunnel" traffic will be scanned by the other apps as it traverses untangle so those users will get Web Filtering etc.

Reports

  • Intermediate "events" schema removed
  • Incremental reports process removed
  • Event log queries now have no delay
  • Removed "Full Refresh" button in event logs (Refresh is a full refresh now)
  • Moved Syslog configuration to reports (this is where the logic lives)

Kaspersky Virus Blocker

  • Officially End-of-Life.
  • On upgrade it will be removed.
  • "Virus Blocker" replaces it.


Functionality changes

HTTPS/HTTP configuration

The "Administration" regarding HTTPS/HTTP access settings have been simplified. HTTPS is no longer open/closed based on other settings, there is simply a setting that controls whether it is open or closed. The HTTPS port settings are now global. Previously when the HTTPS port setting was changed it only changed it on certain interfaces and kept it at 443 on other interfaces. This was not intuitive behavior and it interfered with port forwards. Be aware if you have changed the HTTPS port you will only be able to administer untangle through the HTTPS port you specified - not 443!

Limiting Administration to IP range

This functionality has been removed from config->administration because it is redundant. All it did was add packet filter rules to limit 443 access on WAN interfaces to the specified IP range. You can now accomplish the same thing by just adding those rules directly to config->networking->advanced->packet filter. Add one rule to block port 443 (or your admin port) access on the WAN interface(s). Then add one rule above that allowing access to port 443 on your WAN interface(s) from the desired IP range.

Report generation

The settings for which reports to generate on which day have been simplified. The daily and weekly are now just checkboxes and you can check the days you want each generated. The monthly reports are just a checkbox. These settings are not 1:1 with the old settings so the conversion will keep your settings as close as possible to the original.

Reporting users

In reports, you can add users that do not have administration privileges, but do have access to reports. Depending on when you setup these accounts you may need to re-enter the password for these users on upgrade.

Syslog

Reports now sends all events via syslog as JSON Strings. Syslog configuration is now configured in the reports UI.


Architectural Changes

Settings files

All settings are now stored in files in /usr/share/untangle/settings/* instead of the database. This is part of an ongoing effort to simplify Untangle and also paves the way for more centralized management of Untangle settings for those users with many Untnagle instances under management.

For power users settings can easily be copied or edited in /usr/share/untangle/settings/.

This also allows us to remove the database dependency from all of Untangle except the Reports application. This paves the way for having the database stored on an alternate server or a server in the cloud. This scenario can be better for large sites with large storage needs for events or for small sites with tiny boxes with no hard drive.

Hibernate and Events schema

The intermediate "events" schema has been removed. Events are now written directly to de-normalized tables in the "reports" schema. This means there is no incremental reports process that runs every few minutes to shuffle events out of the intermediate schema. This should significantly reduce the disk i/o requirements on large sites and also remove the delay from event logs.

Hibernate (the java persistence library) has also been removed. Events are now written using SQL directly to the reports schema. Event logs are now queried using SQL. This simplifies the code.

System Requirements

We continue to focus on reducing the hardware and system requirements. 9.3 requires significantly less disk I/O and should also use less memory.
