cfos6link 2.00 build 1076 -- 12-May-2009
* Major changes in cfos IPv6 Link:
cfos IPv6 Link is now a NDIS filter driver for network cards.
At load time cfos IPv6 Link performs an auto-detection of the
connected network devices and switches into one of the following
modes:
- Router mode: If cfos IPv6 Link detects a router or DHCPv6 server it
uses this device to route data to the Internet.
- Dial-up mode: If cfos IPv6 Link detects a PPPoE node connected to
the network card (e.g. via DSL) it establishes a PPP/PPPoE
connection to the Internet provider either automatically or on
demand.
- Mixed mode: If cfos IPv6 Link detects an IPv4 DHCP Server attached
to the network card (regardless of other IPv6 devices), it passes
all IPv4 traffic through to this IPv4 Router.
This allows simultaneous use of IPv4 and IPv6. Windows prefers IPv6
by first trying to resolve an address to an IPv6 address and only
uses IPv4 if no IPv6 address is (yet) available. IPv4 is thereby a
fallback for IPv6.
Mixed mode is possible with routers that support "PPPoE
Passthrough", e.g. Speedport. Then the IPv4 traffic travels as usual
to the IPv4 provider, while IPv6 traffic travels via PPPoE to the
IPv6 provider.
* Flexible negotiation of all IPv6 parameters / DHCPv6 Prefix
Delegation:
cfos IPv6 Link is now also a DHCPv6 client to the Internet. Thereby it
can determine the IPv6 prefix not only by router advertisements, but
also by DHCPv6 Prefix Delegation. We tested it (among others) with a
Cisco Router. Thanks to cfos IPv6 Link ISPs can now employ the Cisco
proposed DHCPv6 Prefix Delegation with their end-customers.
cfos IPv6 Link can now also acquire DNS addresses via DHCPv6 (in
addition to using the option in Router Advertisements). In Mixed mode
the address of the IPv4 DNS server is also used. Thereby cfos IPv6
Link uses all possible ways to access DNS servers, without the need
for manual configuration.
+ VLAN support for Dial-up connections and Router mode.
Configurable DHCPv6 DUID. Thereby a DHCPv6 server can assign certain
previously determined parameters to the client system, identified by
the DUID.
+ DHCPv6 Stateless Configuration. Allows the ISP to transmit DNS
addresses of the DNS servers independently of the IPv6 prefix.
+ Added additional way of allocation to relieve non-paged pool.
- Added code for post mortem debugging.
x Fixed potentially serious bug in interlocked handling.
cfos6link 1.02 -- 17-Nov-2008
x Fixed driver load problem.
cfos6link 1.00 -- 14-Nov-2008
+ Speeded memory allocation.
+ If you begin you prefix with an !, the prefix option in router advertisements is ignored.
+ Workaround for Cisco AC "payload length" bug. Thanks to Oliver Döring, Titan Networks.
+ PPP / PPPoE errors are now indicated in the Status line in the context menu.
+ cFos IPv6 Link now evaluates Router Advertisements from the ISP. It adjusts
MTU and Prefix (64bit only) accordingly. It also checks for the DNS option (rfc5006)
and can set DNS1/DNS2 addresses if present.
x Fixed some Windows object security problems.
x Entries in connections.ini were sometime active only after a reboot. Fixed.
x An active connection is now also indicated by "IPv6" in the tray icon under Vista.
- Upgraded compiler.
cfos6link 0.91 build 1043
- Initial beta release.
