Hi Dave,

I tried the steps you provided and at the end I see that its the port 22
not listening

qrouter-5fc00c74-9277-4ddb-998e-2872ed2b3c90



[root at lspal117 ~(keystone_demo)]# ip netns exec
qdhcp-5af3918a-8848-4678-9bf0-dcfcba5b280e ssh root at 192.168.2.0
ssh: connect to host 192.168.2.0 port 22: Network is unreachable



Any ideas how to resolve to ssh to tenant IP: 192.168.2.0 from openstack
SSH. 
FYI< last 2 days I did fix some issues and I was able to logon to SSH of
the tenant instance via floating IP: 10.48.146.119 but I cannot ssh to
tenant private IP: 192.168.2.0 from openstack node ?



Best Regards,

 

Rushi.
