Access to the Internet for private VPC subnets is possible across a gateway instance providing VPN access to the customer network and allowing (NATted) Internet access via this path. Alternatively, a NAT gateway in the cloud can be used to map the private addresses to public addresses. The NAT gateway can be implemented on a Charon host system or it can be provided by AWS for a charge.
Please note that the Charon host always needs either direct Internet access or Internet access via NAT from a NAT gateway in the AWS cloud to access the license server.

Direct Solaris guest access to the Internet:

1. Create a configuration file (/etc/sysconfig/network-scripts/ifcfg-<interface-name>) for the second interface (if there is no configuration file for the primary interface, create it as well).
2. Set the correct interface for default route in /etc/sysconfig/network (example: GATEWAYDEV=eth0).
3. To prevent the cloud-init from resetting your custom network configurations, add the following lines to the /etc/cloud/cloud.cfg file:
   network:
  ; config: disabled
4. Restart the network.
5. Create an additional routing table (use the command: ip route add <path> dev <interface-name> table <table-id>). There must be an entry for every IP address assigned to the second interface and any other route to be used.
6. Set rules in the Routing Policy Database (use the command: ip rule add from <ip-address-of-second-interface> lookup <table-id>)
7. Create a static route file (/etc/sysconfig/network-scripts/route-<interface-name>)
8. Create a static rule file (/etc/sysconfig/network-scripts/rule-<interface-name>)
