Can't connect remotely.

[Saffire]

For some odd reason I cannot for the life of me connect to my copy of Ahln sitting on my server at home. However, I can run an entirely different MUD codebase on the same server, running on the same port, and connect to it with no problems. Here is my current setup:

At the top of my network I have a taryon cable modem. I run a cable from that into a Trendnet TEW-432BRP wireless router, and a cable from that connected to my server. The rest of the computers on the network connect wirelessly (This shouldn't make a difference, but I add it for the sake of completeness). The server is assigned a static IP address of 192.168.1.50, every other computer on the network is assigned a dynamic IP address.

Whenever I try to connect to the MUD (Which is running on the server 24 hours 7 days a week) via telnet I get the following error: "Could not open connection to host, on port 23: Connect failed."

I have tried running the game through port 23, port 4000, and port 10000. I have set up port forwarding for each of those ports and set them to forward to the server's dynamic IP address. I have also tried connecting with port forwarding turned off. I have put the server's IP address into the router's DMZ, which also yielded no results.

My ISP is not blocking connections from port 23, 4000, or 10000.

If I run another MUD codebase from my server (A Python codebase, if that matters) I can connect to it remotely on any of the ports I've been trying. It should also be noted that Ahln runs on the server flawlessly, and even connects to it locally.

Based on the above, I can only conclude that there is some problem with the codebase when connecting remotely.

The server is running Windows XP Professional service pack 3, ruby 1.8.6 (One click installer for Windows). One oddity is that for some reason I couldn't force it to install Eventmachine 0.12.2, so instead I went with Eventmachine 12.0 (i386-mswin32), it seems to work perfectly.

Any ideas?

The address used in the server configuration needs to be your external IP address.

[Saffire]

Oh, duh! Thanks. But when I set it to my external IP address it does this:

after it's done this it stalls a bit, and then restarts, rinse/repeat.

Ah, right. Because it can't bind to that address, either. Hmm...I've solved this before, I just can't recall how. You can try using "localhost" or "0.0.0.0" and see if those work.

Essentially, the host name/IP address of the server needs to be the same as the one the client uses to connect to it, plus it needs to know that address refers to the local machine.

[Saffire]

localhost and 127.0.0.1 both work. That's my public IP address.

Hmm. I'll look into it more in-depth after work.

[Justin]

Have you worked this out yet?

Turns out my router was misconfigured when I was looking at this before, plus I was out of town so things were weird.

I've tried this out at home, on Windows. Configuring it to use "0.0.0.0" appears to be the only address that works properly (allows connections from the local machine, local network, and from the other side of the NAT).

[Saffire]

I haven't had time to look at it much yet, I've been out of town, I get back on Sunday.
