I have read the stuff on 6over4 and such and still a little confused on a few things: 1. The machine I want to do the tunneling on is behind a NAT'ed firewall how do I reliabelly obtain the external IP of the firewall (dhcp assigned from cable company)? 2. If the machine I want to do the tunneling with is the DMZ host for the above FW do I need to add anything special to the FW's routing tables? 3. I am a little confused on how to pick the other end of the tunnel and how do I configure it once the first 2 items are solved?... The confusion comes from how is an arbitary (by me [with in the restrictions in stf(4)]) selected IPv6 IP supposed to be routable when IPv4 forces me to use the one assigned to me by my upstream router? -- Aryeh M.
