Tower!3D Pro Multiplayer Connection Problems - RESOLVED

[futureboy]

Doing multiplayer when trying to connect the server is started and waiting for connection is displayed, the client goes to join but after about 10-15 seconds the message "not connected" comes up. Further attempts are unsuccessful.

Pinging the "server" is successful with 62ms response times:
----???.???.???.??? PING Statistics----
92 packets transmitted, 92 packets received, 0% packet loss
round-trip (ms)  min/avg/max/stddev = 62.0/63.10/72.2/1.61

Traceroute gets as far as the ISP in the "servers" city then times out, which is probably expected.

Router is set to forward any IP address on port 21112 to serve

In playing multiplayer with Tower!3DPro the only way a connection could be established is if playing on a local network or through a VPN using Hamachi by LogMeIn.

Am I missing something? Between four of us we have not been able to connect to each other.

Since it is late Friday, I'll give you guys a couple hours to hash through the problem :)

P.S. Would the game.log file from the server or client have any information?  
The server game.log file shows:
Platform assembly: C:\Program Files (x86)\FeelThere\Tower!3D Pro\tower3d_Data\Managed\System.Configuration.dll (this message is harmless)
Platform assembly: C:\Program Files (x86)\FeelThere\Tower!3D Pro\tower3d_Data\Managed\System.Xml.dll (this message is harmless)

Uh-Oh, liar, liar, pants on fire :)  I fingered it out, thanks to tcpdump:

Of course this was on a local network, waiting for someone to get online to test the WAN.

Vic, I'm going to steal Ricky's thunder but we have found the issue with Pro multiplayer. It is using port 22222 instead of 21112. We'd appreciate an emergency fix or a fix as soon as possible to correct the issue.

We were never able to connect using port 21112, but when we changed the rule to 22222 we then were able to connect. But as discussed in the following thread, http://forum.simflight.com/topic/82796-tower3d-pro-multiplayer-port-assignment/ port 22222 is not a good port to use. The thread mentions it was fixed, but looks like it needs to be fixed again.

Thanks, Craig  

PS - The online manual still references 22222 in one section and 21112 in another.
