Hi,


IOS SSL VPN doesn¹t currently support IPv6 for SVC. See Features Not
Supported on the Cisco IOS SSL VPN
<http://www.cisco.com/en/US/docs/ios/sec_secure_connectivity/configuration/
guide/sec_ssl_vpn_ps10591_TSD_Products_Configuration_Guide_Chapter.html#wp1

It works quite well on ASA with the exception of not being able to supply
IPv6 name servers so you can't pretend to have IPv6 only connectivity.
Also, at least with OS X, if you have IPv6 on the LAN and then enter SVC
and enable your tunnel, when you disconnect your IPv6 connectivity on the
LAN wont work anymore.
