Client connector cannot access host in 100.64.x.x range

Hello,

I installed two APP Connector on AWS (Docker).
These App Connector needs to establish RDP/SSH sessions to various hosts (AWS, Azure, On Premise).
Sessions (RDP or SSH) to 192.168.x.x (On PREM) and 100.67.x.x (Azure) are working.
Session to AWS Host in 100.64.0.0/19 or 100.64.128.0/19 are NOT working.
PS : the Security group applied to RDP/SSH servers and App Connector is fully opened (traffic cannot be blocked)…
When I look into the APP connector client GUI, It seems the counters is not increasing when I try to reach 100.64.x.x hosts.

What’s the problem ?

100.64.0.0/10 is the shared address space. ZPA uses it for traffic forwarding. You will see it if you look up any ZPA Application on a client. As it is not working I would assume that this is the reason.

Hi,

Thanks for your help.
In fact, it seems the Zclient connector cannot access 100.64.x.x range…
