Another try. I'm hosting for years for my squadron and these are the main showstoppers:
- your pc, when hosting, host must have a
static IP in your home net, otherwise
the port forwarding in the router would "point" to the wrong PC. Check if the ports
are open.
- host enters 0.0.0.0 in the comms window as your IP. Your router will transmit all network packets
because of the forwarding rule.
- the client must enter your "outside" IP. You can check for example with:
http://www.heise.de/netze/tools/meine-ip-adresse/ This address is usually given by your ISP and usually
not static, has
to be
checked every time you want to host and to be re-entered by
the client
- host and client must run the same version of BMS
- host and client must select/run the same theatre
- host and client should uncheck the IVC boxes first to
take IVC out of the way
- the Windows firewalls must allow the external/public comms for Falcon BMS,
it is ok to disable firewalls for a connection test, but don't forget to re-enable
Hope this helps. If still no joy, install "wireshark" to sniff your network to check
if any network packets from the client arrive at all.
