Dear All,

The PCS7 version i am using is PCS7 V7.1 SP4

I am using Security Scalance S623 to establish communication between DMZ Zone and Internal Zone. I have OpenPCS7 station in DMZ zone and OS Server in Internal Zone. 

I have set the firewall rules to access these two PCs i.e. OS Server and OpenPCS7. I am able to ping and i am able to share the folders in between these two PC's.

But when i open OPC Scout as client on OpenPCS7 machine and try to access the OS Server. I get the error as attached here. Also i have attached the OPC Scout Log as well.

Can anyone tell me, why i am getting this error? What kind of settings we need to do for Firewall to get access the OS server?

Please help.
