Hi all,
I have a private network set up at home. I have a linksys router that I
connect my cable modem to and have 2 PCs connected to the linksys
router. Now, I have a one way cable but that should not affect my
question.
When I connect to the internet my linksys router is given an IP address
from the cable(ISP). Say this is u.v.w.x. Although the PCs that are
connected to the linksys router have IP address 192.168.x.y (private
addresses). Now, I am able to access the internet using both the PCs.
Say for example, I am doing a http request, how does it know that the
reply needs to be send to me. It cannot send the source address
192.168.x.y as that is private to my network. So, it should be taking
the IP address that the cable modem provides it and sending out the
request, then when it gets the response how does the router know which
PC to send the response to.
Is the question clear or am I missing something very trivial.
thanks,
Krishnan.
