IMPORTANT
SNS 3.x versions have reached End of Maintenance since July 1st, 2024.
We recommend that you update your SNS firewalls to a version with maintenance to guarantee the protection of your infrastructure.
Getting Started
Product concerned: SNS 1 and higher versions
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.
