Cant connect to my External IP???

[dsheller]

m_m, one question.
Are you doing the following:

Internal Comp A  
            v
Internal Comp B

Or as follows,

External Comp
           v
  Your Router
           v
Your Internal Comp

If it is the one below, then you have to use something called NAT (Network Address Translation ) to forward the ports to the correct internal computer:

IE If you are using port 1337 to connect to on the internal machine then you must forward from the Router => InternalComputerIP. I am not sure what router you have, but snoop around in it you can probably figure it out.
