Port forwarding problems with unconventional broadband

Barno · 29 Jun 2007 at 16:33

Hi,

I've just had a new broadband connection installed and am trying to forward some ports. The problem I have is that it is not a conventional connection. As I live in a broadband blackspot the service here is esentially wireless but when it reaches the house it becomes a wired connection. It is beamed out from a pole up on a hill to a box on the side of the house, and then from the box it is wired into the house and to my PC via ethernet. As far as windows is concerned I'm running off a LAN. Does anyone have any idea how to forward ports with this setup? Would I need to put my own router in the middle somewhere? The box on the side of the house is effectively a router but I have no access to it from my computer.

Thanks.

Not entirely sure about the port forwarding but I am more interested in the way youve got your connection

How did you come accross this setup? Was this a solution given to you by a company? Or was it just something you rigged up yourself?

What kind of distance are we talking about?

From the dish on the pole it must hit some sort of router. Where exactly is that broadband source coming from?

What does your IP address begin with? Just the first octet would be enough.

Thanks for the replies.

The service is provided by a company as BT aren't looking to upgrade the line here till 2009 at the very earliest. The pole attached to a tree on a nearby hill (high tech stuff this) where the connection is beamed out is approx. 1-2 miles away. So far I'm extremely pleased with the service - 8meg+ in the middle of the South Downs aint bad!

The pole beams out the connection which is received by an aerial on the side of the house, this feeds into a box containing (as far as I understand) a mini-pc running linux which acts as a router. From there the connection is wired via ethernet into each flat where it connects to my PC, again via ethernet, and appears as a LAN.

DHCP is enabled so the IP as of now is 89.248.136.10.

You should be able to install a normal router at the point of entry onto your network, much the same as any "normal" broadband connection? My cable connection comes in via cable, hits the cable modem and then my router.. the CM is 83.xxx.xxx.xxx and the router takes it from there, yours *should* be exactly the same (but different IP) unless the linux router throttles or cuts off certain ports to your IP address?

I assume you have a different IP address to any of your neighbours and it isn't a shared one?

I don't think the IPs are shared, although I think there may be multiple firewalls along the line at the router box and at the source of the connection itself so even if I did forward the ports on my router I may need to request the ports opened further up the line.

You mind me asking who the company is?

Your using KIJOMA.NET and I think your right, your ports issue will be dictated by whatever devices the supplier has to put in place to deliver and secure your connection. Its likley your effectively inside their company network and they have control.

You need to ask them what they allow and only worry about a router for yourself after you have confirmed that they can provide the service your after and that you need to share that IP

Is there are particular software, service or port causing problems?

You could try enabling Upnp on your PC and see if that helps compatible software thorugh any firewall you or they might have.

Thanks for the replies. Sorry it took me so long to get back to the topic.

Yes, you're right, I'm using Kijoma. How did you know? Also, how would I enable upnp on my pc?
