Question about Netgraph (I'm in a mess :)

[Juan Rodriguez Hervella]

Hello,

I'd like to make some modifications to the IPv6 hearder of some packets
before sending them out the interface. I'm thinking where's the best
way of doing this. So, I've found out the Netgraph tool (I didn't know it 
before :) but now I'm wondering how to use it properly.

As far as I understand, I could have a "ng_iface" node which would
have a "ipv6" hook to my new node, which would change the IPv6
packet.... I would grab the packets installing a new route towards the
"ng_iface" node, right ? Then, if I want to insert the modified packet
to send it out the interface, I should connect my new node to the
"ng_ether" node ? or again sending out the packet through the same
"ng_iface" node ? 

I'm a bit mix up with all this stuff, any help will be very appreciated.
