Hello Everyone,

I recently got a new fiber optic internet connection and have a few question on setting things up.
I do not have admin access to the modem/router given to me by my ISP.
If i plug in an ethernet cable from the router to my laptop everything works.
I only know the default gateway and the DNS servers, which i got from typing ipconfig /all.
The default gateway is 192.168.100.1.
Its been 2 months since i got the new connection and the gateway address has not changed?Can i assume it to be static?


Now i have two routers ,one is the Netgear D6300 and the other is an ASUS RT-N 12+ router
I want to cascade both my routers to the main router.
I have done the following:

On the netgear router,i connected an ethernet cable from the ISP's routers LAN port to the netgear router's WAN port.
In the WAN settings on the netgear router ,i only entered the primary and secondary DNS servers which is same as the default gateway address of my ISPs router.
Result: I am able to access the internet without any issues.

On the Asus router:
I changed the router address to 192.168.100.2 I connected a LAN cable from my main router to a LAN port on the Asus router.I also disabled DCHP services on the Asus router.
Result:I am able to access the internet.

All my devices on either of the routers have a fixed ip address.
With the above setup i am also able to access data from a computer connected to the netgear and another computer connected to the Asus router.!!!!
I would like to know how this is possible.The netgear connected pc has an IP address of 192.168.0.5 and the Asus connected pc has an IP address of 192.168.100.7!!!!

Now what do i do if i want to access my data over the internet??I havemy gaming rig connected to the Asus router,what information is required so that i can access its file systems over the internet?

Many thanks,
Arun

You will not be able to access the files on your computer from the internet without admin access to the ISP modem/router. 192.168.100.1 is a private address (only public addresses are accessible on the internet) and you would have to use port forwarding through the ISP modem/router to access anything inside your network.

Your home network actually consists of 2 networks ... 192.168.100.xx & 192.168.0.xx (I am assuming you are using a netmask of 255.255.255.0). Computers that are on 192.168.0.xx send packets through 192.168.100.xx to get anywhere, so they are able to find computers with 192.168.100.xx. Unfortunately, computers on 192.168.100.xx do not know how to find the 192.168.0.xx network, so they can not access them (unless you have set up some routing or something). If you want all the computers to be able to access each other then they should all be on the same network, which you can do by plugging from your ISP LAN port to a LAN port on the netgear (don't forget to turn off DHCP on the netgear). Then all your computers should be on the 192.168.100.xx network.
