Got problems with my network (Cisco 805 Routers)
I got 3 site with four machines each:
All the machines on the sites has the same IP addresses. This is something that I am not allowed to change.
Machine 1 : IP 20.0.1.24 Machine 2 : IP 20.0.1.25 Machine 3 : IP 20.0.1.10
I have alos a fourth site that should be able to access all the 9 machines. The problems is that they use the same IP addresses.
My solution is to use static NAT:
Site 1: ip nat inside source static 20.0.1.10 10.0.1.10 ip nat inside source static 20.0.1.24 10.0.1.14 ip nat inside source static 20.0.1.25 10.0.1.15 Router LAN IP 20.0.1.1 ip nat inside Router WAN IP 10.0.1.1 ip nat outside Site 2: ip nat inside source static 20.0.1.10 10.0.1.20 ip nat inside source static 20.0.1.24 10.0.1.24 ip nat inside source static 20.0.1.25 10.0.1.25 Router LAN IP 20.0.1.1 ip nat inside Router WAN IP 10.0.1.3 ip nat outside Site 3: ip nat inside source static 20.0.1.10 10.0.1.30 ip nat inside source static 20.0.1.24 10.0.1.34 ip nat inside source static 20.0.1.25 10.0.1.35 Router LAN IP 20.0.1.1 ip nat inside Router WAN IP 10.0.1.4 ip nat outside
On site 4 my routing table looks like this:
I do know that some classless subnetting would be better for the size of my routing table... ip route 10.0.1.10 255.255.255.255 10.0.1.1 ip route 10.0.1.14 255.255.255.255 10.0.1.1 ip route 10.0.1.15 255.255.255.255 10.0.1.1 ip route 10.0.1.20 255.255.255.255 10.0.1.3 ip route 10.0.1.24 255.255.255.255 10.0.1.3 ip route 10.0.1.25 255.255.255.255 10.0.1.3 ip route 10.0.1.30 255.255.255.255 10.0.1.4 ip route 10.0.1.34 255.255.255.255 10.0.1.4 ip route 10.0.1.35 255.255.255.255 10.0.1.4
All my routers is available to ping all the machines in the network. My PROBLEM is that the clients on the LAN are not able to reach other clients on different sites. All clients has 20.0.1.1 as default router.
Is my NAT configures correctly? Am I allowed to use the IP address I use? This is a totally private network and is not connected to the Internet.
