According to RFC 4215 ,If we need to support tunneling feature in UEthan ---> host-to-router (automatic) tunneling mechanism can be agood fit. ---> but there is no consensus on right approach Currently ISATAP, 6to4 and Teredo are automatic tunneling technology.Only Teredo can work over the NAT. ISATAP is implemented in Microsoft Windows XP Because of a patent claim, early implementationswere withdrawn from both KAME (*BSD) and USAGI (Linux). ISATAP also carries the same security risks as 6over4: Please let us know which tunneling approach will be most recommended for3GPP Mobile host.I am unable to find any relevant RFC's and DRAFT other than RFC 4215.
