The modem/router my ISP provided me with assigns an external IP address to every device in the home network. Every computer/phone etc. that connects to it either via network cable or wireless gets a static external IP.
When I check what is the gateway I get the same result - an external address (85.91.X.XXX - ifconfig, ipconfig) It doesn't do anything when entered in the browser address bar, neither does 192.168.1.1.
I understand when most people look up their gateway address, they get a local number; they also have a browser utility for configuring their device.
I'm trying to connect my Dreamcast console to the internet. It doesn't have a network adapter, only a phone line modem. In order for the console to access the web I have to connect it back-to-back to a computer with a phone line modem; Then configure the computer to share it's internet connection with the dreamcast via modem. Essentially I'm turning my Linux machine into an ISP.
These are the tutorials I'm following:
I have everything set up, the modem is detected on "ttyLS0". Mgetty, gnome-ppp installed correctly. I created a user account for the Dreamcast as well.
However I'm having difficulty figuring out what IP addresses I should enter in the following two files:
Where the line "ms-dns 192.168.1.1" (third from the bottom) should be my gateway, the INTERNAL address of my router.debug
#IP Addresses. Uncomment whichever one you wish to use
#router IP for internet browsing
#sylverant PSO server
The second file is
Here I need to provide the internal address of the computer giving the connection : the IP address I would like to create for the Dreamcast which has to be "within the same subnet" as my PC.192.168.1.101:192.168.1.105
The problem here is that the computer has an EXTERNAL address within the home network, therefore I can't create an address for the console. Or can I?
I'm a casual GNU/Linux user, so please correct me if I got something wrong.
