port forwarding port ranges and ipv6 tunneling

I'm currently setup using nat overloading on a 3620 and have a few ports static forwarded which is working great. my question is how would the ip nat syntax differ to forward a range of ports for say pasv ftp? could someone provide some examples? I'm also trying to setup ipv6to4 tunnelling to hurricane electric and i've configured the tunnel with a couple different setups. I can ping6 the internal /64 gateway but i'm unaware why my router is unable to ping the ipv6 endpoint at he. Any suggestions there would be welcome aswell. I've included a copy of my current config below which is most likely a work in progress :) Thanks in advance.
