Cannot SSH to an NFV internal IP Address

You can SSH to an NFV instance's internal IP from instances in the VNET but not from outside the VNET.

To resolve the issue, follow these steps:

1. Connect using the console to the NFV instance and log in with the following credentials:

   • Username: root

   • Password: ThinkAgileCP

2. Execute the following command to edit the sysctl.conf file:

   vi /etc/sysctl.conf

   After, type i to start editing the file.

3. Add the following line to the end of the file:

   net.ipv4.conf.default.rp_filter=2
   

4. Press ESC and type :wq to save the changes and close the file.
5. To load the changes to sysctl, execute the following command:

   sysctl —p

You are now be able to connect via SSH to the internal IP address of the NFV instance from outside the VNET.
