pfSense

Allow for creation of a ipv6 tunnel for he.net by creating a gif interface. This is the recommended procedure as advised by he.net
This allows for using ipv6 local and remote addresses, you will need to add a ipv6 default gateway on the routing tab

Switch over the IPv6 functions from IPv6.inc, these are from the PHP PEAR library

up the subnet bits from 32 to 128 so that the access can be locked down to the host for ipv6.
This will require a javascript routine that prevents a subnet mask higher then 32 bits for a ipv4 address.

Alternatively the subnet bits should be steered by javascript to prevent use of more then 32 bits on a ipv4 address. When a hostname is used all bets are off, even worse if the hostname is a combined ipv4/ipv6.

Fix the filter.inc rule generation for icmp to prevent a double inet6 in the rule
Add inet6 for user defined rules to ipv6 addresses.

Change the firewall rule generation to look for the ipprotocol tag which defines inet or inet6. This makes sure that we use ipv6 addresses and change to the correct ipv6-icmp tag.

Add a rule so that the bare icmp ipv6 traffic can get out, otherwise the box can not communicate properly on ipv6

tack on the ipv6 information via the old fashioned way until the pfsense module is up to speed

splay the IPv6 information on status interfaces.

fix filter rule error

remove some debugging from filter inc, show correct ipv6 gateway from function
