Abstract

The embodiment of the invention provides a message transmission method in mobile IPv6 and UTM (unified threat management) equipment. The method comprises: forwarding a DNS (domain name server) search request transmitted by an MN (mobile node) to a DNS server; after a DNS response returned by the DNS server is received, revising the IP address of the communication node communicated with the MN and carried in the DNS response to a virtual IP address configured on the UTM equipment, and transmitting the revised DNS response to the MN; receiving a message transmitted by the MN, wherein the target address of the message is the virtual IP address; carrying out UTM processing on the message transmitted by the MN; and transmitting the message processed by the UTM to the communication node. After the MN leaves a home network, the embodiment of the invention ensures that the transmitted message still passes through the UTM equipment to guarantee operation safety and service smoothness.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to a message transmission method and UTM equipment in mobile IPv6. Background technique [0002] With the maturity and trial operation of the IPv6 standard, introducing IPv6 into the mobile network has become an important development direction of the communication network. Mobile IPv6 technology is an important part of IPv6 technology. It makes full use of the inherent support of the IPv6 protocol for mobility, and can search for mobile nodes (Mobile Node, MN) through the Home of Address (HoA) in different mobile networks. Mobile IPv6 is completely transparent to the protocol layer above the IP layer, which makes the application program running on the node need not be modified or configured to still be available when the mobile node moves between different subnets. [0003] When the mobile node is connected on its home link, it works in the same way as a general host or router. W...
