I took a capture on my network between the firewall and the app server. I have been seeing a lot of duplicate acks. But the duplicate acks never go past one and they are always from the firewall. It seems like the firewall is just trying to catch up to its buffer. I never see fast retransmissions or retransmissions. How many duplicate acks in a period of time is to much?
