Thanks, and so she be where some may look:
iptables -I FORWARD 1 -m conntrack --ctstate RELATED,ESTABLISHED -j FLOWOFFLOAD
Nope: for me it keeps resetting an established connection; my irc client. I will check my image contents again.
With image from config.seed, running on rango target, my irc client(irssi on an ubuntu box) continually resets its connection every few minutes upon installing FLOWOFFLOAD.
Should maybe add that the irc connection is a secure connection.
The latest series of patches addressed this issue, things appear to be working.
