I'm on Windows XP SP3 and basically my topology consists of 3 computers (see drawing for more detail), a wireless connection to the Internet and a wired connection to a router. My main computer (A) is connected to the Internet (I) using a wireless USB card and the main computer is also connected to a router (R). The other two computers (B and C) are also connected to the router and the router itself is not connected to the Internet. I just want to use the router to connect the three machines together (a LAN) in order to send TCP packets (using BOOST-ASIO) from the main computer to either of the other two machines (which by the way are not connected to anything but the router that also connects to the main computer).
Network topology drawing:
A - Main computer with two connections I and R. This machine needs a subnet mask fix.
B - Computer connected to computer A through router R.
C - Computer connected to computer A through router R.
R - Router.
I - Internet.
I R------ \ / \ \ \ / \ \ A B C
The trouble I'm having is that I tried this setup already but I need to setup the subnet address on Windows XP somehow (I did search the Internet but nothing specific came up just the theory of subnet masking). My setup basically chooses the connection under the network connections->advanced settings-> network bindings and I cannot get both my LAN and Internet to work together?
They don't seem to explain the details on Toms Hardware either =(.
