One configuration that might explain that is that some(many? most?) DSL & Cable modems have USB connections as well as Ethernet. So the Mac could be connected via USB and then plugged into a generic hub with Ethernet which also has the PC.

It's definitely a Hub. There is only 1 ethernet wire from the Mac to the hub. In this setup the Mac actually does serve as a router, it distributes IP addresses to the other machines on the network. This is a built in feature of OS-X (I believe). I'm having trouble locating the equivalent of setup page that you would normally be able to configure on a router. The setup page where I disabled the firewall is fairly basic... though perhaps that's all that's available.

I tried b50 and b54. b54 gives the "cannot load campain"
b50 gives the error: "IO Error: java.net.ConnectExeption: Connection refused: connect"

Wohoo, more info:
In the spirit of treating this like a router, I opened up http://192.168.2.1/ in my web browswer. The following page came up:

Quote:
If you can see this, it means that the installation of the Apache web server software on this system was successful. You may now add content to this directory and replace this page.

.... blah blah blah

The Apache documentation has been included with this distribution.

You are free to use the image below on an Apache-powered web server. Thanks for using Apache!


.... right, so Apache is a web server application??? Ok, I'm officially out of my comfort zone now. Anyway, this is all the info I've got for now.

As I mentioned yesterday, I'm actually flying away so it's really not important for me to get this setup working with maptool. I just thought it might be interesting if we could troubleshoot this. Sorry, I won't be able to test anything else.

I do know that the underlying software allows incoming and outgoing ports to be filtered separately and I know that packets coming into the machine are routed through a "forwarding" layer and then back out, so there are three levels of filtering (input, forward, output) and all three must be properly configured, but I don't know the details of what the "Internet Connection Sharing" actually does.

Perhaps this is the problem. I'll be dammed if I can find where to configure them on the mac though.

It would be unusual for a home user to have two computers connected to a hub and use connection sharing on one of them. Since both are connected to the hub, both can reach the outside world directly. In fact, Linux systems will actually report a bogus routing table entry if you ping a machine on the same physical network when the packet is routed through another machine on that same network. (Essentially, it's reporting a misconfigured LAN.)

The reason both computers don't directly reach the outside world (i'm told) is that our internet provider has only provided the house with a single IP address. If we had more we wouldn't need the mac to serve as a router and assign IP addresses to the other computers.

Ok, gotta go catch that plane! :?

Hi to all,
i'm trying to figure out how to start a server while i'm in my home network.
My ISP provider id Fastweb, an italian ISP.
They give me a NAT connection, and my ip address is invisible from the outside.
I always used Hamachi to get rid of this problem, but with MapTool it seems that the old good Hamachi can't save me.
I moved Hamachi as the first network adapter in the list, but MapTool still takes the LAN adapter by default... i dunno why.

Is there a way to make my MapTool server work?

thank you in advance ;)


I up this thread because one of my players does have this problem too.
I've read all, but I didn't understand: is there a way we could workaround this issue?

This problem would not affect players, only those trying to host a server(unless the router was royally screwed up). You need to provide detailed information on the GM host's network configuration as well as the players and what does and does not happen. My initial guess would be to check the network FAQ for network card settings on his machine need to be tweaked.

I save all my Campaign Files to DropBox. Not only can I access a campaign file from pretty much any OS that will run Maptool(Win,OSX, linux), but each file is versioned, so if something goes crazy wild, I can always roll back to a previous version of the same file.

Get your Dropbox 2GB via my referral link, and as a bonus, I get an extra 250 MB of space. Even if you don't don't use my link, I still enthusiastically recommend Dropbox..

Well, I am trying to host a server.
I read the FAQ and I think I fall in the case number 6: I have a server running and both wired and wireless local clients can connect (via the 127.0.0.1 IP), but not clients that are on the Internet.
I read the answer, but I don't understand how I can do the following:
This can be tested by removing your router from the network completely and plugging your Internet connection directly into your MapTool server machine.
My router model is Thomson, TG784n (ISP Tiscali - Italy).
If you need more info please tell me to!

Thanks in advance for any help!

Sometime people mix up what a router and a modem is. The modem translates the data and establishes a connect to your computer or a router. The router is the traffic cop that tells the data where to go. If you have 2 devices, 1 modem and 1 router, then unplugging the router from the modem and connecting the modem to your computer is what step 6 suggests. Sometimes, the modem and router are the same device. In that case, you don't have the option of removing the router. Then sometime the modem part is handled somewhere else (you don't have the hardware in the house) and you just have an rj45 cable coming from the wall. Plug that directly in to your computer.

In your case, you have an integrated modem, so you can't really remove the device. You need to log in to your device and find port forwarding or port triggering. For port forwarding, you need to either set each computer with a static ip, or there may be something on the router to allow address reservation based on the mac address of NIC. This would be under a topic like LAN IP Setup. Port triggering is the same, but you specify a range of addresses and when one of those address makes a request for that port it will be routed. See if your supports UPnP, that is the easiest way but b87 has a bug and doesn't support it currently. Make sure to check or uncheck the UPnP when starting a server based on how you're connecting (UPnP or port forwarding).

I see but how could I set my computer with a static ip? I looked for a topic in the forum but I found nothing...
