The HOST address out in internet space will be your Router's external IP address (probably assigned by your ISP, i.e. something like 24.34.122.56 ).

Firewall issues: By default, most firewalls block all incoming packets that are not a response to your outgoing requests. You need to ensure that the required transmission ports (TCP, UDP) are unblocked from your firewall/router and your host allowing packets going out, and allowing external Clients to transmit packets to you.

Routing issues: Then, you need to ensure that from your router the "Service" (by Service -- e.g. 192.168.1.1:1200 ) is routed to your local server (i.e. 192.168.1.100). In other words, when your router gets packets of that type (i.e. 1200), it needs to know that it should pass it along to your (192.168.1.100) server. Your local server will get external clients traffic (request packets) via the routers address, and then reply (response packets).

I usually troubleshoot my home server hosting issues by either working with a remote friend, or by accessing/investigating my home IP address from work (From home, I can VPN to work, and sniff back to my home network via remote).
