Abstract
During the period of co-existence of IPv4 and IPv6, Ipv6 over IPv4 tunneling technique is intended as a start-up transition mechanism. However, most of IPv4 firewalls do not support the IPv6 over IPv4 tunneling packet filtering. Finally, it is impossible that a user inside IPv4 firewall connects with an IPv6 host across IPv4 network. Without any additional hardware or changing the policy of IPv4 firewall, we solve this problem using proposed Double-encapsulation and applied-HTTP tunneling technique that are end-to-end solutions. This enables cheaper IPv6 migration solutions.
