-* VPN and IPv6
-
-The internal VPN capability should support IPv6. Essentially, the D-Bus
-interface between NetworkManager and the VPN service daemons should be extended
-with an IP6Config signal that passes up the IPv6 addressing and routing details
-if the VPN daemon is IPv6 capable. NM should then process those details like it
-does with IPv4. include/NetworkManagerVPN.h should be updated with key/value
-pairs defining the various IPv6 attributes much like the IPv4 ones are defined.

* VPN IP Methods
Some VPNs (openvpn with TAP for example) require that DHCP is run on a
it tracks which network connections are active, and it already queries the
network for automatic proxy configuration via DHCP and WPAD.
+However, proxy handling is complicated and may require use of Javascript to
+parse PAC files provided by WPAD, and this is not something NetworkManager
+should do itself. Instead, that should be left to "proxy handlers", or external
+utilities like libproxy or pacrunner that take raw proxy information, parse it,
+and tell applications what proxy server to use for a specific network resource.
+NetworkManager should provide all the proxy information it can find to these
+external proxy handlers via the D-Bus interface and dispatcher scripts.

We should add a new NMSetting subclass called NMSettingProxy that holds
necessary proxy configuration. The properties of this setting should be a
superset of what is provided in the Firefox proxy configuration screen and the
After completing IP configuration but still during the NM_DEVICE_STATE_IP_CONFIG
activation stage, NetworkManager would merge the automatically supplied proxy
configuration (from DHCP's WPAD option) with user-provided overrides from the
-NMSettingProxy and send the results to the system. The 'default' connection's
-proxy configuration would be preferred, so we'd have to update proxy
-configuration from nm-policy.c the same time we update DNS information and the
-default route.

+exported over D-Bus as a property of the org.freedesktop.NetworkManager.Device
+interface. This property should be named "ProxyInfo" and should have the
+D-Bus signature "a{sv}" (eg, dictionary) and should mirror the properties from
+the NMSettingProxy object.
- libproxy: need to figure out how it gets proxy info and have NM write merged
- proxy config out to that location
- pacrunner: a D-Bus enabled daemon, NM would call D-Bus methods of the

the best route to go for desktop use-cases as well. Instead of bringing all

Consequently the same behavior should be used when a better connection becomes
