Creating a bridge from ADSL router to WLAN router
Hi all,
I'm not really sure if the term bridge is even the right one for what I need, so please bare with me on this one. My current network setup is as follows: Code:
Ubuntu Linux box I don't have static IP address. My ISP provides the IP, which changes almost every 3-5 days. The IP I currently have in linux box is 91.155.190.121, where in PS3 I get 192.155.179.211 I suppose the difference in the IP address explains why I am not able to ping/connect these machines together. Is there any solution for this? Please help. I read in some other pages that if I connect the WLAN router with the ADSL router by not using the WAN port, the WLAN router will act as hub, hence the problem would be solved. Well, I tried that one and I still have the same probelm :S |
well the first ip you've posted is an internet ip - so i suppose that is not your linux box's ip but your adsl router's
the second one seems to be a private one so probably the wireless acts as a dhcp server easiest way to get things working is to plug in your linux box into the wireless if it has cable slots which i suppose runs from the adsl to the linux box and the wireless - or connect it thru a wireless card else you are in to a course of basic tcpip - subnetting and setting up dhcp servers also you can tell from what is above that i have to guess a lot so if you want help with setting it up you better get some more info - like what does ifconfig typed in shell on the linuxbox show (there's an ip in there somewhere - that's your linux ip) if you keep with your current setup you have 2 different which should be connected - this should be configured on the wireless veel plezier er mee :) |
Hello jimjones
Thank you for your reply. Due to cabling and signal coverage issues, I am not able to have the linux box connected directly to the WLAN router. Here is the ifconfig output: Quote:

weird
your ip adress behind the adsl router is an internet ip-adress any idea what the ip adress is your wireless uses for connection with the adslrouter? (you can find that by going to a whatsmyip site from your laptop or another wireless device) If thats also an internet ip then i assume your adsl router only allows outgoing connections and doesnt act as a hub routing traffic from wireless to linux box You could try enabling that (your modem - you have the docs i suppose) or even have the adsl rouyer act as a dhcp server or hub for a local network using your own adress space - i.e. 192.168.X.X Just a thought - is this modem provided by your isp? |
Hi,
Here is an IP of one of the machines connected to the WLAN router: 192.155.179.211 Yes, the ADSL modem is provided from the ISP. I'm afraid I didn't understand what I am supposed to do. Would you simplify please. Thanks |

and i suppose you will not be able to configure the adsl router either- so no luck so back to my first suggestion : the easiest way is to get your linux box also behind the wireless good luck |
Hi,
Well, I finally managed to make it work, by following your advice and connecting the linux box straight to the wlan router. However, there is still a nasty issue pending. When I connected the ADSL modem to WLAN router through the WAN connction, the Linux box lost its connection to the internet. The only way I managed to solve is, was by connecting the ADSL modem to the WLAN router through one of the 4 normal hub connections. Any idea why is that? This is of course not the best option for me as I am now losing one needed Ethernet connection of my WLAN router. Please advise. |
Buy a Ethernet switch box and cable it (as an additional hub) to your WLAN router port, thus (assuming a 4 port switch) giving you three additional cable ports to your WLAN. (A four-port switch should be in the $10 price range. That's what I paid in 1998 for the last one I needed.)
