SUBJECT: Change in Port Binding behaviour starting with software release 4.4

MODEL / SYSTEM AFFECTED: cnPilot-R190, cnPilot-R200, cnPilot-R200P, cnPilot-R201, cnPilot-R201P, cnPilot-R201W

REASON FOR BULLETIN: Starting with version 4.4 of the Cambium cnPilot R-series software a fix was introduced related to the port binding. This change requires that users creating non-default WAN INTERNET profiles MUST explicitly enable port binding by selecting one or more LAN ports and/or SSIDs to the created INTERNET WAN profile as needed. Software before 4.4 had an issue where in such situations all ports/WLANs were automatically bound to such an INTERNET WAN profile created by the users.

NOTE: Customers using default WAN profile and running firmware 4.3.4 or lower remain unaffected.

NOTE: Customers using non default WAN profile and running 4.3.4 or lower who have explicitly bound their required LAN ports and/or SSIDs to their INTERNET WAN profile will experience no problems after upgrade. 

RESOLUTION: Users running 4.3.4 or lower software and upgrading to 4.4 or newer software MUST ensure that they update their port binding configuration by explicitly selecting one or more LAN ports and/or SSIDs before upgrading to avoid problems related to Internet access from LAN/WLAN clients. For more details refer to the User’s Guide and/or Cambium Knowledge Base articles on Port Binding.
