only one public IP?

[realdreams]

I want to get IPv6 on several computers but only have one public IP. My router uses DDWRT but the build doesn't support IPv6(someone removed it due to the size of flash). If it has IPv6 support I guess I can set up the tunnel and enable DHCPv6. But what can I do without IPv6 support on the router?
Right now I have the tunnel up on a computer behind NAT. dunno how to bring IPv6 to other computers.  My ISP doesn't provide more than 1 ip address.

Configure something like RADVD on that computer behind nat, and announce the routed /64 that is statically routed to your side of the tunnel.
