I use the standard port (23432) of Fsnav and when I type the server's IP address in FSNAV multiplayer window, I see my local connection sending requests to Internet, I have no error message back, but no session appears and the JOIN button remains definitely grey. The connection log of FsHost does not mention at all my connection try with fsnav, and reports only my connections with FS9. Here is the copy of the forwarding ports of my local router: I have tried to open ports too on the FS Computer. What did I forget? I have checked that the 'Disconnect FsNavigator after.xx minutes' box is UNCHECKED in FsHost config. My Fsnav version is 4.7 and Fsnav multiplayer connections work very well with FSINN connections. First, when I tried connecting with FS2004, it worked fine, as you said. When I tried FSNav on the default port 23432, it couldn't find the session. But when I tried FSNav on 23456, it worked, and it found the session (but of course it couldn't actually connect because of the password, as you said). The short answer is that something's wrong with the forward you setup for 6073. You might want to check it again and make sure it's for UDP, and it's forwarded to the right IP, and is marked as active, etc. If you're not interested in the gory details, you can stop reading here. I watched everything with a packet sniffer and I think I see what's going wrong.

When FS2004 searches, it tries whatever port you have it set to (default = 23456) as well as the 'alternate DirectPlay port', 6073. What's supposed to happen is that the DirectPlay on the FSHost machine will respond to the request on 23456, and also respond to the request to 6073, but when it responds to 6073 it actually responds back on 23456 as well (or occasionally on a port in the 2302-2400 range, I don't fully understand why). But I'm not getting anything back for the 6073 request, so I'm guessing that the FSHost machine is never getting it.įS2004 does something else here also. If you tell it to search on 23456, it searches 234, as I said above.

But if you tell it to search on anything other than 23456, for example 23457, then it searches three ports: 23456, 6073, and 23457. In other words, it always searches on 234, regardless of what you tell it to use, and then it searches on the requested port as well if it's not 23456.
