RADIUS Authentication Error Across the Subnet

Hi Guyz

I have configured Microsoft Server 2012 R2 as a RADIUS for Cisco IOS Devices

Server IP Address :  10.95.6.12

Router IP Address Fa 0/0.192                    ---->>>    192.193.194.195

Router IP Address Fa 0/0.6                          --->>>    10.95.6.1

Switch IP Address VLAN 192                     ---->>>    192.193.194.2010.95.6.11

Switch IP Address VLAN 6                          ---->>>    10.95.6.11

When i access the Cisco Devices RADIUS CLIENT with 10.95.6.x Subnet, It works fine 

When i access the Cisco Devices through RADIUS CLIENT 192.193.194.x Subnet, It does not pass through the RADIUS Authentication.

Attached in the Picture i can not access the 192.193.194.20 Device but I can access 10.95.6.1 Device.  As soon as I change the IP Address 10.95.6.11 I can access the Device.

 

Ping is successful across the  Routers / Switches and Server as well.  Below is unsuccessful debug details as well:
