Ping TNSR WAN Interface from local networkΒΆ

The instance should now be reachable via ICMP echo request (ping) using the Elastic IP Address associated to the TNSR WAN Interface.

To find the Elastic IP address associated to the TNSR WAN Interface, use the EC2 Web Console:

  1. Navigate to

  2. Click Instances

  3. Click the button next to the TNSR interface to select it

  4. Look at the bottom of the page, under the Description tab to see Network Interfaces

  5. Click on eth1

  6. Find the Elastic IP Address field in the popup

Now, try to ping the Elastic IP Address of the TNSR WAN Interface:

bash-3.2$ ping -c 5

64 bytes from icmp_seq=3 ttl=45 time=48.632 ms
64 bytes from icmp_seq=4 ttl=45 time=48.433 ms

Once the Host OS is capable of reaching the Internet, check for updates (Updating TNSR) before proceeding. This ensures the security and integrity of the router before TNSR interfaces are exposed to the Internet.
