Duplicate ACK

Hi,

Digging through some tcpdumps we see duplicate acks coming back with slightly different timestamps.

FW-1 4.1 running on IPSO.

Any ideas/wild theories what would cause this?

Cheers

Hi Brian,
You didn't specify if these double acks are comiing for all types of connections.
Some software use multiple TCP connections to establish one application connection. Is it the case?
