Description
Only one change since v4.4.34, however an important one for some use cases:
– Do not clear IPs from DHCP WAN interface in PREINIT of a forced renewal. The primary problem symptom is when the system is provisioned by the controller when booting up (most always only the first boot post-upgrade).
– In all firmware versions prior to this, that provisioning would remove the WAN IP then go through the DHCP lease process. This would leave a single WAN system with no Internet connectivity for a few seconds at least, and in multi-WAN cases, would cause a failover and fail back. In most cases, that was the only noticable symptom and it self-recovered without any problems, but in some it could cause issues that require another reboot post-upgrade. In multi-WAN cases, it could cause WAN to stay in a down state on the first bootup post-upgrade. In normal operation of the system, there are no forced DHCP renewals (this isn’t relevant to the normal process of DHCP renewal).
Upgrade WARNING:
– If using a VLAN tag on WAN, and on a controller version including port remapping (5.8.7 and newer), you should not upgrade to this version until upgrading to controller 5.8.12, 5.9.3, or newer. For that circumstance, USG must be provisioned by the newer controller version (which will happen automatically post-controller upgrade) before upgrading to any firmware version including port remapping support.
– If you have GeoIP enabled and are not yet on firmware 4.4.18 or newer, disable it first, then upgrade USG, then enable it again. The configuration has changed in a way that limited unstable controller and previous firmware version combinations could result in an invalid configuration on the new firmware versions. In that circumstance, if the upgrade is performed with GeoIP enabled, the system will have to be reset to factory defaults post-upgrade.
Downgrade WARNING:
– If you upgrade to any version supporting DPI without offload, disable offload (or enable IDS/IPS) and enable DPI, you cannot downgrade to a version that does not support DPI without offload. Either disable DPI, or enable hardware offload (or disable IDS/IPS), before downgrading. Otherwise you’ll have to reset to factory defaults post-downgrade and adopt again.
