An NSIS-Based Approach for Firewall Traversal in Mobile IPv6 Networks

Overview

Firewalls have been successfully deployed in network infrastructure in various environments and will also be used in IPv6 networks. However, most of the current firewalls do not support Mobile IPv6, the best known standardized solution for mobility support in IPv6. As a result, Mobile IPv6 traffic will be most likely dropped when used without an appropriate firewall traversal solution. This paper describes the problems and impacts of having firewalls in Mobile IPv6 environments and presents a firewall traversal solution based on the IETF's Next Steps in Signaling framework to address these issues.
