Firewall Traversal in Mobile IPv6 Networks

Middleboxes such as firewalls are an important aspect for a majority of IP networks today. Current IP networks are predominantly based on IPv4 technology, and hence various firewalls as well as Network Address Translators (NATs) have been originally designed for these networks. Deployment of IPv6 networks is currently work in progress. Given the fact that Mobile IPv6 is a recent standard, most firewalls available for IPv6 networks still do not support Mobile IPv6. Unless firewalls are aware of Mobile IPv6 protocol details, they will either block communication traffic under Mobile IPv6, or carefully deal with the traffic. This is a major impediment to the successful deployment of Mobile IPv6.
