Looks like things do not get passed the 9.9.9.0 gateway.

Below I am copying the output for both gateways and for two cases: first where the ping is not successful and then the case where ping is successful. (I can attach the complete output of these files if i can figure out how to do it here.)

Case 1 - Here is the case where 9.9.9.2 on Server A canNOT ping 9.9.8.5 on Server A:

on the 9.9.9.0 gatway:
