Thank you for your wishes. We have developed a tutorial where you can access routers remotely with dd-wrt: http://www.hotspotsystem.com/hotspot_help/kb/articles/70-how-can-i-access-the-router-remotely
We are not the developers of the dd-wrt firmware, other that the tutorial offered we strongly advise you to post a question on the support forum of dd-wrt. A developer of this firmware may answer you with additional suggestions and more specific instructions. The link is: http://www.dd-wrt.com/phpBB2/
