Before anything else, if you have the Mac internal firewall turned on, either turn it off, or ensure the game is allowed incoming connections as follows:

• System Preferences -> Security -> Firewall -> Advanced -> "+" -> GrassGames' Cribbage

[ EDIT: The following should not be needed any more in version 3.2 and later, but won't do any harm... ]


The game tries to open a port on your router to help network games connections. However this may or may not be successful.

You can check if the port is being opened properly are by using the Port Map app by Coding Monkeys - here's the Mac download link: (no Windows one yet, sorry)

http://www.codingmonkeys.de/portmap/download

After you download the app, do the following:

• Start the game
• Select Network Game
• Create a game - this should open a port
• Start the Port Map app that you downloaded
• Press the All UPnP Mappings button
• See if a port has been opened by the game

You can add a port for the game by doing the following (not a bad idea even if a port is listed already):

• Start the game
• Go to Options -> Online
• Note down the port number being used
• Start the Port Map app
• Click the "+" button in Port Map
• Enter the port number in the Local Port field
• Check both TCP and UDP
• Type Cribbage into the Description field
• Press Add Mapping

Now try connecting to people within the game.

Extra things to try:

• There are 4 numbers listed in the online options section within the game - try adding port mappings for all four numbers.
• Change your port number in the online options section to a number between 43000 and 53000, then add the mappings again.

Let us know how you get on!

If this helps I can incorporate all of this into the next version of the game so you won't have add port mappings manually in the future.

I've just tried to connect to 5 Mac players and ALL connected fine with this fix, so please try this solution.

Make sure there are no extra port mappings in the list that are not needed.

I'll have a new version out soon.

Also for those still having problems after using Port Map, you can have a look here to see if you router setup needs adjusting:

I tried all of it and had some success by using port 43000. At least now I am getting something other than connection failed..I will try again tomorrow and post the results.

Version 3.2 and later should now open the ports correctly, so hopefully connections will be better from now on.

There should not be any need to do the points above anymore.

I've tried all the suggested procedures with no luck. I'm using v. 3.2 on a Mac running Snow Leopard. The PortMap app confirms that any of the ports I select are active. Sometimes I get the error message about Ports not being available when I initiate Network, sometimes it loads but then refuses to connect (stage 1). The only part of your instructions that is unclear is the part about the 4 numbers listed in the online options page. All I see is the current port selected and 2998. Am I missing something? I'm a retired software engineer, problem is I retired just as the internet was happening. I'd like a better grasp of what's going on.

OK. I can join a game but can't invite. Ports clearly are open despite error message upon entry. Purchased an iTouch version to rule out software. Same symptoms. If iOS and OSX shared bug would be universal problem. Has to be the WiFi router. Will ask owner of campground for type and model for further investigation.

The new networking system is ready to be tested - see here.
