Issue Description
WP-4043
8.2.22
Issue: You cannot log in to the MWG GUI by using any external managed admin account. Logging in using the local admin account still works.
The following setting is disabled: Accounts > Administrator accounts are managed externally.
If you enable the setting again and save your changes, it is disabled again after some minutes.
Workaround: Use the local admin account.
WP-3868
8.2
Issue: You disable the Enabled Openers rule set and configure the Gateway Anti-Malware Engine as Avira only.
But Avira does not detect specific or modified eicar files inside the archive.
Workaround: Open MWG Policy, under Common Rules, enable the Enable Opener Rule set.
WP-1872
8.2
8.2.1
Issue: In ProxyHA or Transparent Router mode, when a node previously marked Director is set as Scanner and the configuration is saved, the resulting node fails to become a Scanner node. The hastats tool shows this node as Redundant Director instead of Scanning node.
Workaround: When a node previously marked as Director is to be changed as Scanner.
Set the director priority to 0 and set as scanner node. Save the changes.
Log on to the MWG back-end of the corresponding node and execute the command service haproxy stop.
Configure the IP in the HTTP and FTP proxy listeners as 0.0.0.0:<port>.
For example, change 192.168.20.10:9090 to 0.0.0.0::9090.
Save changes.
Solution: Upgrade to 8.2.1.
WP-1870
8.2
8.2.1
Issue: Transparent Router Mode plus IP-spoofing Performance drops. In transparent router mode, if IP spoofing is enabled, a high response time (>250 ms) and connection error is observed.
Workaround:
Perform the following steps every time any proxy-related configuration is updated from the GUI-based manager.
Locate and open in a text editor of your choice the file /etc/haproxy/haproxy.cfg.
Search for the string frontend fwd_proxy.
Under that block, after the line bind <ip>:<port> accept-proxy transparent, enter the new line maxconn 50000.
For example: bind 192.168.20.150:80 accept-proxy transparent
maxconn 50000
Repeat this process for each instance of the stringfrontend fwd_proxy, adding the new line under the accept-proxy transparent entry.
Save and close the file.
Restart the service. Typeservice haproxy restartand press Enter.
WP-1866
8.2
8.2.1
Issue: In transparent router mode, when only the HTTP proxy is enabled and IP spoofing is enabled only for HTTP traffic, the HTTP connection fails with a 502 error. Workaround: Enable the FTP proxy. Enable the FTP port redirects and FTP listener configuration at the same time.
WP-2033
8.2
8.2.2
Issue: MWG 8.2 does not support configuring Transparent proxy in Bridge mode.
Existing customers using transparent bridge mode in older releases are advised to not upgrade to the latest version.
Solution: This feature is supported in MWG 8.2.2 and later.
WP-1813
8.2
8.2.1
Issue: In 8.2, the bandwidth throttling feature in router mode is not fully supported. Using the feature in the router mode might not throttle the traffic according to the configuration. Existing customers using this feature in transparent router mode in older releases, are advised to not upgrade to the latest version.

Issue: You can't paste text when you use the Webswing user interface with the Edge browser. You press Ctrl+V, the paste fails, and you see the following error:
SCRIPT5007: Unable to get property 'getData' of undefined or null reference webswing-embed.js (145,464897)
Issue: When you update MWG from a version earlier than 7.7.2.14 or with the AV rollback flag (ud-rollbackGAM2015) enabled, MWG 8.0 can't load the old GAM2015 libraries. Instead, it downloads the new engine in the background. This process can take several minutes, depending on your download speed. Users see the error:
Cannot Load Anti-Malware Engine The Anti-Malware engine could not be loaded and your administrator doesn't allow to deliver content without being checked for viruses.
Please call your administrator with the error message below.
Solution: Do not redirect traffic to MWG before the AV engine has finished all updates. You can view the update status in the MWG dashboard.
