Security Issues
When tunneling, be sure to increase the protection of your network by using firewalls. You can use a hardware firewall or a client software firewall.
Unlike IPv4, IPv6 does not use the network address translation (NAT) functionality to connect to the external network.
To avoid exposing internal devices directly on the external public network, you must configure the IP firewall on the gateway. For information about configuring the IP firewall to properly manage traffic destined for the internal network, see IP Firewall OS Design Development.
