It's becoming good practice to enable IPv6 for your services, as the IPv4 address pool is almost depleted. In some countries, regulations even require municipal and governmental organizations to adopt IPv6 within a very short time, which is complicated by the surprisingly large amount of network products that doesn't support IPv6 properly. The matter becomes worse when it comes to anti-spam filters, which typically relies heavily on IPv4-based blocklists, and the fact that the spam rate is even higher for IPv6.
All our products support IPv6. In fact, they were designed with IPv6 in mind.
Our anti-spam e-mail security gateway is an excellent way to introduce IPv6 for your e-mail (SMTP), without the risk of increases in spam. First of all, it handles the IPv6-to-IPv4 translation, thus enabling you to receive and send e-mail on IPv6 without making any changes to existing infrastructure. Secondly, it's one of very few e-mail security gateways to fully support and effectively block spam on IPv6. It even handles IPv6 on connection (IP reputation) level.
Our firewalls, or security router series as we prefer to call them, simplify IPv6 adoption, deployment and migration by providing a wide range of flexible IPv4/IPv6 translation technologies; both on layer 4+ which allows for advanced rewriting and on layer 3 which provides an unique, protocol independent IPv6 translation. It can be used to enable IPv6 for IPv4-only users, implement NAT64 for internal networks, and much more.
