Cannot SSH to NFV's Internal IP

Problem: You can SSH to an NFV instance's internal IP from instances in the vnet, but not from outside the vnet.

Solution:

  1. Open a console to the NFV instance and login as root with password cloudistics
  2. Enter vi /etc/sysctl.conf and type i to edit the file.
    • Add a line: net.ipv4.conf.default.rp_filter=2
    • Type ESC then :wq to save the changes and close the file. 
  3. Run sysctl -p
  4. You will now be able to SSH to the NFV instance's internal IP from outside the vnet.
