    Hi All,

    I was wondering, is there a general problem accessing
    a service that’s running inside a LAN network, using the external IP ?

    what i mean is .
    station A is running an http server on port 80 for example
    and has a relevant PAT / port forwarding rule on the router directing port 80 traffic to it.

    could station A access its own http server using the external ip (the router’s IP on port 80)
    could station B, that’s on the same simple LAN ,
    access station A using the external IP:80 ?

    if not – why not ?
    is there some sort of NAT limitation on this ?
    or is it an ISP issue ?

    (i’m talking about simple home routers
    if there are any other routers that can overcome this
    issue, i’d love to know how they do it)

    thanks.
