netgear Router 6250 and port forwarding

> i'm trying to port forward and did it right but somehow it dosent work

   I and the other non-psychics in your audience might wonder:

   What is the actual problem which you are trying to solve?

   What, exactly, did you do?

   What, exactly, happened when you did it?

   What kind of "dosent work" is this?  What, exactly, fails?  How,
exactly, did you determine that port forwarding wasn't working?

> and i was wondering if having upnp on would make any trouble for me

   Based on no actual information, how much useful advice on this topic
were you expecting?
