Port wont forward to dreambox dm500s

**ramjet** · 20 January, 2012, 16:20

the windows wont have any bearing on the router forwarding ports to the dreambox

basically , you forward 12000 to the dreambox fixed ip address , with both TCP and UDP , and allow wan to open it

if the dreambox is actually using say cccam or oscam and the port is set to open , and if the outgoing cs is running , the dreambox will open the port and cs

if no active emu is running the port will be closed as the dm hasnt opened it

so you need an active emu to tell the dm to open the port , otherwise its shut by default

same applies with torrents , your torrent program opens the port when you are sending stuff

no port has to be opened when receiving , just sending

just remember you are forwarding the port to the dm so it can open it , so its being FORWARDED , not OPENED

then run cccam or oscam and set the port you are activating , so that the emu opens the port due to sending cs

hope that helps

Thanks for the reply

I have ccam 2.2.1 running on the dreambox

I have no cs running at the moment

So are you saying that if someone tried to access my server then the port will open and let them in, but otherwise the port will be closed

Is that what you mean, or did I misinterpret?

no , its the other way round

if you are using a card and actively sending out on F lines , the dm will open the port in order to send from cccam

if you have no F lines , and/or no card , so are not actively sending stuff , the port remains closed

ie:- its only open for the time you are sending and they are connected , not all the time and definitely not if you are only receiving and not sending

Ok I get you now, so if I put a f line into my ccam and then check the port again I will know.

I was also have one more question:
I set up a no-ip host, but I was wondering what ip addres do I put in. I read somewhere that I put in the address of my router. So, I put in the local ip of my router, 192.168.1.1 is this correct?

And then in a friends cline I would put: myserver.zapto.org.no-ip.com
Is that correct?

Thanks a lot ramjet, I have spent so long trying to figure all these things out

dyndns and no-ip require your router ( or pc ) to login periodically and inform them of your actual ISP ip address , not your router ip

your friend would have your hostname , port , name and password in his line , so he connects to no-ip , and is forwarded to your server as the host knows your isp ip address

the router then forwards it to the port server ( your dm )

I think you need more than just an F line as I think you would have to have the emu sending from a card , worth a try without a card but I am assuming it needs an active cs going out 9 not just an F line in the cfg )

**davidom2513** · 20 January, 2012, 19:55

Ok, thats great, I understand. Thanks a lot

Do you know how to set up a cs proxy or do you think its worth it?

And what do you think is safer, private or payservers. And how can you maximise the safety

Thats not quite correct. If you open a port on the majority of routers then its open regardless of what the dreambox is doing. When the dreambox isn't running cs the port is still open even though the dreambox isn't responding. External internet requests are still allowed through the router and inside your network - they just wont get a response as the server isn't running. The router itself doesn't know or care if a server is actually listening it will simply do as its told and route all traffic for a particular port to the given device.

In that respect port forwarding is the permanent opening of a port and the routing of that port to a specific internal NAT address. If you want 'triggered' port opening then it will generally be under a different name ('application rules' or somesuch name) but that will rarely work with a standard server as they mostly just sit there and listen for requests, they never actually initiate requests (thus they cant trigger anything).

To a large extent you can consider port forwarding to be a limited version of a DMZ where only a single port (or specified range of ports) is left open and routed to a specified device instead of all ports.

What do you suggest I should do TheCoder? Have you any ideas that I could try to get the port to open? I had my hopes up that I was almost there :/

I have followed all the guides religiously, so it is very odd that the port is not open, its very frustrating

Would it be a router error or is there a way around this.

Because from what you have said my setup will not work until the port is opened

**davidom2513** · 20 January, 2012, 21:29

Should I bother trying port triggering? Or would I be wasting my time? I found it here in the router settings?

Or what do you suggest I do?

**cgscott** · 20 January, 2012, 21:30

Why not just try a different port number? Closer to 12000

**davidom2513** · 20 January, 2012, 22:41

I tried 12000 there and it won't open either

Any other ideas would be very much appreciated

**TheCoder** · 20 January, 2012, 23:29

Some routers seem to have problems opening high-numbered ports. I'd be inclined to try a port number below 1024 - you could try something around 915.

Generally Linksys routers tend to do what they are supposed to do so I suspect your problem is a misconfiguration of something somewhere.

Does the router know you've set static ip's on devices ?

As well as filling in ip details on the devices themselves you'll also need to inform the router that those devices are pre-allocated to ip's (usually by giving the router their mac addresses and ip address). You may also need to allocate addresses outside of the modems dhcp pool but within your subnet (ie, if your modem allocates ip's 192.168.123.100-199, then use 192.168.123.1-99 for your static addresses) - this ensures the modem doesn't try to allocate one of your statics to another device.

How are you testing if the port is actually open ?

Very few applications can tell the difference between a closed port and an open port with unresponsive server. If you can tell this difference then you'' likely be able to spot the fault easier as it will point to either router configuration or dreambox server configuration.

Open Port Check Tool is the site I use , and I have several ports forwarded to various boxes , with 2 to my dreambox , both dm ports are currently open and it says SUCCESS in green , the others are firmly closed

so what I wrote earlier is my experience of this both when setting it up and when testing ports for cs

**davidom2513** · 20 January, 2012, 23:56

No I havent told the router that I have set staic ip addresses. Is this the screen I use to do it? (see screenshot below)

My dreambox is set as 192.168.1.25 and my computer is set at 192.168.1.104

This is what I'm using to test if the port is open: Open Port Check Tool - Test Port Forwarding on Your Router

Let me know if thats the right screen to fill the static ip's on

Thanks for your help
