Networking Mac nerds needed!

[Disco Dan]

Running a program called "Transmission" which is a bittorrent program and running Mac OSX 10.5.3


Now need to open the port up but cant figure it out!

Using ethernet connection to a D-Link 502T

Nothing comes up in the debug log in transmission when I toggle auto map port check box.

Always says "port is stealth" regardless what numbers i put in.

Router allows me to setup however when I go to click 'apply' it says:

"please select a End Map as asn integer"

So what am I doing wrong??

see if that helps you

Try using a number from 1,000 to 10,000. 50,000 might be too big for it.

Yeah i used ports 4000-8000 for my torrents otherwise my "Go Large" goes small

Not really a Mac Nerd required then is it.

go Apple menu > System Preferences > Sharing > Firewall > New > do as you wish to open any port

Two things.

1. Firstly, Port forwarding is the process of opening path between your computer and the internet for a program to do a particular task. In this case, Transmission for torrent transfer.

2. There are typically two places where ports are blocked (firewalled) so that data cannot be passed through them. Namely your computer and your router. If you have a seperate adsl modem and router, then that would usually make 3 places. What you have to do is make sure every device is letting data through the port you want.

3. On your Mac, under OS X 10.5, go to the security section of system preferances and click on firewall. Here you can tell OS X's software firewall to let traffic pass for a particular programme. OS X's firewall only deals with traffic coming in. To block traffic going out you need a third party application such as Little Snitch. Add Transmission to the list and set it to 'allow incoming connections'. Alternatively just turn your firewall off alltogether if you're not worried about it.

4. Now for your router. Your setup details look correct. So my bet is that your router cannot handle ports this high. Just go about trying to setup in the same way a port in the 8000-10000 range. If it works, that's great. if it doesn't then you are not doing it right.

5. If it doesn't work, then try using a preset from your first picture, and modify it to suit.

6. If it does work, great. All you need to do is now go back into the Transmission preferences and change port 50001 to whatever port you chose to forward in para 4.

Hope this helps.

P.S. I'm a mac fanatic. I know a little bit about networking, but heaps and heaps about home theatre, movies, codecs, music, OS X file structure, etc etc when it comes to macs. Any questions just pm me.

P.P.S. If anyone knows how to create a software bridge from Ethernet to Wireless (not using Share Internet Connection which isn't really bridging) on their mac please pm me.

Sorry, somehow posted twice. Must be because I'm doing this from a Windoze comp!

Alright, according to your screenshots, you've cocked up with the Port Map thingie. I have a DSL-G604T, same front-end more or less. What you want is to enter the values as follows:
Port Start: 50001
Port End: 50001
Port Map: 50001

That's what the error message is saying -- it wants an integer (a port number, like 50001), you've given it a strange thing with decimal points in it (an IP address). By `End Map' it means the ending port to map to (not Port End, that's confusing) -- the Port Map is the local port to forward to -- you are saying, forward all ports between Port Start and Port End to Port Map. You enter the IP address to forward to in a field called Private IP. I can't see the box for Private IP in your screenshot -- it's supposed to be there, even with G502Ts, perhaps it'll pop up when you click on Apply; NZ/Aus firmware is often a little behind.

Cheers for your help, I managed to alter the wrong thing and lost internet until this morning.. real smart ay!

Anyhoo, Firewall is set to allow all connections for program.

Tried changing port number to:

**** ***** ***** **** but no luck - Transmission still shows it's status as "port is stealth".

Ok got it going, and all sorted cheers everyone for your quick replies!!

Quickly looking through the net, it appears Transmission rates pretty poorly for its port mapping techniques causing headaches like what you experienced even when everything is configured correctly. Glad to see you got yours running though. For everyone else, I recommend Azureus, but running in advanced mode so you don't get the crappy vuze interface. Azureus has pretty good port testing features.

I like Transmission as it allows me to automatically speed limit the downloads/uploads during certain times of the day. This in conjunction with Xnet's new "torrent" plan makes for a pretty neat package
