tcp dup ack in excess (#170)
I'm trying to troubleshoot some weird behvior on my network. It is composed of a PC, a switch, another PC (HyperV) and a VM.
Trying to browse internet from that VM is on some websites, not displaying anything (website load an infinite time). Doing the same from my PC, I have no issue at all.
So I started wireshark and as a test, I did a file transfert (4GB) from the VM to the PC, from the PC side. I recorded both captures.
1) Captures show TCP DUP ack, growing up to 170+ (in 20ms)
2) Captures on both sides doesn't show the same TCP DUP Ack count, suggesting somebody is filtering something.
3) Sequence number trace show clear flat stops in the curves, at many points.
I can provide captures if needed.
Can you please help me understanding what may cause this ?
