I am having an issue in my network where i cant access my internal network from out (Internet).
My network topology is as follow.
PC 1 uses a Public IP ADDRESS
The Link between R1 and R2 is Privately addressed.
Also the link between R2 and R3 is also on a private address range.
Link between R3 and Internet is Public and i can reach the interface on R3 pointing to the internet.
R3 is configured with NAT.
PCA uses public Address which is routed thru a private network to the internet router R3 configured with nat.
From PCA i can go to the internet. But i would like to accesss PCA from the Internet.
I am thinking it is the NAT that is blocking. Because from the Internet i cant even Ping PCA.
I only have default routes on the routers R1 R2 and R3 to the internet router.
How can i reverse, because i am think static routes would help.
