All Amazon EC2 servers have a
routing feature activated by default. This feature drops any packets being sent to the server which have a destination different from the machine's IP address. If the VPN solution selected for connecting agents to the JON
server includes a router, this feature needs to be turned off for the server or servers acting as routers or VPN gateways. This configuration setting can be accessed via the Amazon AWS console. Disabled
is also required in a Virtual Private Cloud (VPC).
Some VPN configurations route general Internet traffic through the corporate VPN by default. It is recommended that you avoid this as it may be a slower and less efficient configuration for your particular needs.
While the use of a proper addressing schema is not a concern specific to JON, poor schemas can affect it. Amazon EC2 assigns IP addresses from the
10.0.0.0/8 network. Instances usually have a public IP address also, but only network traffic on the internal IP address within the same availability zone is free. To avoid using the
10.0.0.0/8 network in private addressing, there are a few things to consider.
