Check out if qrouter got floating inside network namespace (ip net
exec qrouter... ip -4 a), or just bash in to it (stdbuf -e0 -o0 ip
net exec qrouter... /bin/bash) and play with it like with normal
server.<br>

<div>Assigned a floating ip to an instance. But I can't ping the
instance. This instance can reach internet with no problem.
But I can't ssh or icmp to this instance. Its not a security
group issue. </div>

<p class="">I can ping 192.168.122.193 using: ip netns exec
qrouter-34f3b828-b7b8-4f44-b430-14d9c5bd0d0c ping
192.168.122.193</p>
<p class="">but not 192.168.122.194 (which is the floating ip)</p>
<p class="">Doing tcp dump on the interace that connects to
the external world, I can see ICMP request but not reply
from the interface :</p>
