Oskar,

I am quite confused. Does the issue happen only after resume from hibernate?
Initially you havn't mentioned hibernate/resume. Are you able to
reproduce the issue without hibernating? Please flush ip table entries
and test.

sudo iptables -F

Can you please take a sniffer capture at the problematic time? Are you seeing huge
latency for ping (icmp)?
