Hi - Nice troubleshooting and finding the actual root cause for your end-user symptom :-) Some options to run past the LB vendor (sorry not a LB expert) 1. Does your LB offer any form of GSLB capability in addition to the source-ip persistence? i.e. Redirect users to the same PCS gateway not just based on source-ip but based on the geo location of their source IP? That way even if source IP changes it still detecting that the user is from a specific location is sending them to the same gateway. If that is not an option you may consider creating multiple connections so end-users are directly hitting individual PCS devices. https://gateway1.domain.com, https://gateway2.domain.com Its not ideal from usability however if the issue is occuring frequently and breaking access for your end users then it may be acceptable to degrade usability slighlty in favour of availability.
