My setup is:
IXIA -- CPE -- router -- IXIA
I have one end of the IXIA connected to CPE, and getting private IP (DHCP from CPE). Other end is connected to router side and has public IP. Traffic upstream from CPE to router is okay. Traffic downstream from router to CPE is not okay.
Any pointers on how to get IXIA to work in this NAT environment?
