My VPN users are able to access IPV4 resources, but not IPV6, all of my other user who are not VPN users are able to access everything V4 and V6. Can anyone help me figure out what I have configured wrong?
However, in your case, you’re using Cisco AnyConnect. Hence, it is possible to support IPv6 through a Cisco VPN Client connection by using host-based tunnels (dynamic or static). One example of this is to leverage Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) (RFC 5214) on the remote client along with an established Cisco VPN Client connection.
Remember that ISATAP is a host-based tunnel that can provide tunneled IPv6 connectivity between the host and a router, Layer 3 switch, or server. The idea is that after a Cisco VPN Client connection has been made, there should be a routing path between the host and the tunnel endpoint located inside the enterprise network. The Cisco VPN Client enables tunneled traffic through the IPv4 IPsec connection.
