On my local network I can access the server just fine and eveything is peachy
king. (the server is on a RH Lynix with ports 80, 1111, 1935, and 8500 open).

However, when I have my router forward these same ports (from the internet), I
can not connect to the FCS/FMS from the outside world. I assume these ports
are used to establish a connection which is then moved to another port. If so,
I should have to open some additional range of ports to be forwarded as well.
Is this correct or am I barking up the wrong tree?

If so, what is the valid range of ports I need to forward?

Additionaly, I was uner the impression that 1111 or 8500 was used for the
FCS/MCS admin consol. Is that true as well? If so does the admin consol need
an additional range as I can not connect to it outside the local network either.

Hi,
First Is this FCS/FMS 1.5 or 2
I have 1.5 on one box and it works fine from outisde the network but 2.0 does
not (i think this is a developers license restriction).
The ports you have are fine (and that proven since they work within your local
network).
If you have FCS/FMS 2.0, you might want to try it with 1.5 on another box and
see what happens. If the problem still persists, your ISP might be blocking
ports.
