Curiosity got the better of me: I just sent you a private mail to the 
same effect on the misdefined constant.

The modem gets a real IP externally, and provides a NATed network 
internally: you can use the on-board webserver to do reasonable decent 
NAT config as well. The device seems quite capable: I've been able to 
SSH to my local net from the outside world, and use a windows VPN client 
to talk IPSEC to a remote network through it, so it's reasonably savvy 
to tunneling issues.

I must confess my knowledge of  IPv6 is less than stellar (I've been 
working in telecoms too long: I've only just forgotten X.25). If you 
want me to try anything, gimmie a shout, but you'll probably get it 
working yourself first...
