Last update: January 2017

SNS firewalls allow Network Address Translation (NAT) to be applied on incoming and outgoing traffic in IPsec VPN tunnels.

The NAT feature in IPsec VPN may come in useful in several situations:

• Interconnecting networks with overlapping address ranges. For more information, please refer to the section Interconnecting networks with overlapping address ranges.

• When you wish to hide the real address range of your LAN. For more information, please refer to the section Hiding an address range.
