Problem: You can SSH to an NFV instance's internal IP from instances in the vnet, but not from outside the vnet.
- Open a console to the NFV instance and login as root with password cloudistics
- 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.
- Run sysctl -p
- You will now be able to SSH to the NFV instance's internal IP from outside the vnet.
