Hi guys dont know if any of you know how to go about this but im having a bit of a dilema.

Im on my Mac upstairs connected to the web via a D-Link ADSL Router/Modem, I want to forward a port but I dont know how, I have admin access to the router so no worrys in this department, and im able to confi it from up here, but I just dont know what to do. Ive tried to turn on UPnP but the router once restarted resets this ang goes back to normal and turns it off. DMZ mode is disabled so it asks me to forward the port manually. Which is on 9090, but im unable to fin out how to do this as im not a networking expert.

The model of the router is DSL-G624T, im trying to set up a mass storage network device so The pc and Mac are able to gain access, and maybe even the PS3 give time and a little linux work. but so far no joy.

Any help would go down a treat.
 
Port forwarding on a DLink (mine, anyway) is on the Advanced tab, then the firewall button on the left. You tell it what IP on your network is hosting the service on that port.

Problem is, that has nothing to do with making it available to computers on your network. Port forwarding through a router is to give access to that service on your network to people on the public Internet, which is not what you're talking about. The router does not block traffic between devices on the LAN, it blocks access to your LAN from the public network. However, if your PC is running firewall software, that software may be blocking traffic.

What is the mass storage device? Can you access it from either the PC or the Mac, neither, or both? It needs an IP address that's on your network (and not already in use) and I'm guessing that's the problem.
 
wfooshee is bang on the money. This is not a router problem. This is a firewall problem on the devices on the local network.

Port forwarding allows a router receiving an inbound request from the internet to forward that request to a device on the local network.

And you probably don't want to allow everybody on the internet to access your mass storage network device.

It sounds to me like a firewall issue, or the device does not have a proper IP address assigned.
 
Thank you for the response, much apreciated. The problem is like this.

1)Mac and PC need to access the mass storage device.
2)PC is hardwired but Mac needs access via WIFI.
3)PC is using windows firewall but sees the port ok.
4)Mac's firewall is off and so is the router's but Mac says the port is not accessable!!! (dont have a clue)

Havent got a clue what the device is, I got it from a buddy, and it worked fine on his setup. TBH i think im going to give it up as a bad job, as im not that way in mind, things like this go over my head.
 
Just out of curiosity, can the PC and Mac talk to each other?

Also, what is the mass storage device connected to? The router, or the PC?

My pc and mac dont have any type of connection that I know about, but im sure I can set up some sort of connection, but to be honest im not the bothered about that, yes the storage device is connected via the router, so that I can access the files whilst on another pc or mac at a friends house, but my connection has to be on. Now I cant access it throug hthat either at the moment, since this port is not open to be accessed. since the pc is hard wred to the router it seems to be able to find it. I think i have to configure the router via the pc since every time I do anything on the mac to it, it dosnt save it, im guna have another go tonight if not im just going to use the storage thing hardwired to my mac.
 
The Mac's access to the router is no different to the PC's just because it's wireless. Wireless is just an invisible cable, there's no functional difference to the connection.

Possible exception: I've seen routers that put the wireless network on a separate LAN. For example, the wired might be 192.168.1.x, the wireless might be 192.168.0.x, and any access between the two would have to be configured. Both networks get Internet access, but not necessarily to each other.

If you can find your Mac's IP address, and your PC's, we can determine whether they're on the same LAN or not. If they are, there should be no problem. If they are on different networks, well, there's your problem! There will be some config option on the router to allow traffic between the LANs, or to put the wireless on the same LAN with the wired.

If the storage device is like many I've seen, it's basically a Windows server in a box, with a web login for management. If you're a l33t haxor you could remote desktop to it for administrative-level access. Some of those have special considerations for Macintosh users, some assume the Mac knows how to talk to Windows.

Mostly right now we need to see if the MAC is on the same network with the PC and the box.

Edit: Checking D-Link's site, I looked at the manual for your router, and it does not separate the wireless and wired networks. They are the same LAN, so the Mac should see the other devices. Can you ping their IP addresses?

How do you access the storage device from the PC. Is it by browser, file explorer, or an application?
