That has nothing to do with your using static IP addresses for your local LAN, 
I do the same thing here, preferring that to dynamic addressing, why will be

A first step and needed on the individual machine hosting the server.

Not exactly. If your cable modem was setup by your ISP to serve up two 
separate IP addresses, which most are not (sometimes you can purchase a second 
IP for a fee monthly), you could feed the modem into an Ethernet switch (not a 
router) and pull one IP from the machine connected to one port of the switch, 
and a second IP to the router connected to the other port (and it's output 
feeding the rest of your LAN.) In this case you would need your ISP modem set 
to serve up two IP addresses, not the one you are likely getting now.

Really though this should not be necessary.

The reason that your machine cannot be seen directly from the Internet at 
large is that your router is doing NAT (network address translation) and as 
you discovered, your internal (private) LAN address is not accessible from the 
Internet. 

What you need to do is (and this is why using static IP addressing on your 
local LAN was such a good idea) is to port-forward the ports needed to operate 
the server through the router direct to the machine hosting the stream. Any 
modern router can handle this with ease.

Some routers have a DMZ sort of feature that puts one and only one machine 
directly on the Internet. But you can't share the IP with other machines while 
you are doing this.

Just determine which ports need to be forwarded to the serving machine, and 
whether the protocol is TCP or UDP and forward these to the machine you want 
to host the stream on.

When you are done, delete the port forwards.

Simple and it'll work like a charm. You can continue to share the Internet 
connection using the usual protocols with the other machines on the network.
