Only to reply to myself here, I've not seen response yet.

I've now also tested the patched stf interface from hrs at . I tried 
getting it online using the 6rd prefix from either ATT or SwissCom but 
neither establishes 2 way comms.

I see packets going out onto the wire proto 41 to the 6rd relay. And if 
I ping the IPv6 address from a remote end I see proto 41 traffic 
arriving in on the external interface from the 6rd relay.

I never seem to be able to establish 2 way communications. e.g. Ping/dns 
etc.

Pcaps here:

http://iserv.nl/files/pfsense/6rd-2.pcap

Note that both the SwissCom and ATT use a /28 prefix. I am not sure if 
the patch takes that into account. I see that 6rd prefix lengths over 32 
bits are not supported either way, which is a shame because there are 
actively people rolling that out.

The pcaps do seem to indicate it takes the /28 prefix into account, but 
I'm not sure from reading the code.

Can anybody see any light at the end of this (6rd) tunnel?

Kind regards,

Seth Mos
