I may attract the wrath of batsam with this, but I had to say something.
Complete disregard for forum unwritten rules, lazy replies and, as someone noted, treated the kindness of forum users as a search engine.
Not cool and I have to give you guys credit for continuing to reply, in spite of the douchey attitude of the o.p.
I fully agree with all that has been said above by the helpful guys in the forum.
I would even go so far to say, that, based on batsam's questions and refusal to take good advice, he probably lacks the necessary technical background to fiddle around with an OpenWrt based router. Better choice for him would be to buy any COTS device and use the firmeware as provided by the vendor. Quite some of those vendors provide a proprietary dial-in service via a Webserver of their own, handling each and everything necessary (DynDNS, Authentication, etc).
Sorry for my harsh words, but that's how I felt when reading through the post and comments.
