Testing the configured feature 1:1 NAT
1. Testing the accessibility between an Ethernet device of machine network 1 and an Ethernet device of produc-
tion network (
“Simple scenario” if you have only 1 Router for testing)
Note:
You can use a PC for simulating an Ethernet device (machine) of networks 1. Use a second PC to be a member of
the production network.
Ensure that the PC simulating machine 1 of network 1 is configured using following parameters:
IP: 192.168.1.100, net mask: 255.255.255.0, Standard Gateway: 192.168.1.254
Ensure that the PC of production network is configured using following parameters:
IP: 172.16.1.20, net mask: 255.255.255.0, Standard Gateway: 172.16.1.252 (pointing to WAN port of
your Router)
1.1 Try to to send a ping request from machine
1
(192.168.1.100) of network
1
to PC of production network
(172.16.1.20).
Result:
PC of production network should reply the “ping request” with original reply IP address
172.16.1.20.
1.2 Try to to send a ping request from PC of production network (172.16.1.20) to machine
1
(192.168.1.100) of network
1
by using the public IP address 192.168.
20
.100.
Result:
Machine 1 of network 2 should reply the “ping request” with reply IP address
192.168.
20
.100 (due to configured 1:1 NAT).
2. Testing the accessibility between Ethernet devices of machine networks 1 and 2 according to the described
application scenario (using 3 Routers)
Note:
You can use PC’s for simulating the Ethernet devices (machines) of networks 1 and 2.
Ensure that the Ethernet devices of both machine networks are configured using following parameters:
IP: 192.168.1.100, net mask: 255.255.255.0, Standard Gateway: 192.168.1.254
2.1 Try to send a ping request from machine
1
(192.168.1.100) of network
1
to machine
1
(same IP 192.168.1.100) of
network
2
by using the public IP address 192.168.
21
.100.
Result:
Machine
1
of network
2
should reply the “ping request” with reply IP address
192.168.
21
.100 (due to configured 1:1 NAT).
2.2 Try to send a ping request from machine
1
(192.168.1.100) of network
2
to machine
1
(same IP 192.168.1.100) of
network
1
by using the public IP address 192.168.
20
.100.
Result:
Machine
1
of network
2
should reply the “ping request” with reply IP address
192.168.
20
.100 (due to configured 1:1 NAT).
Note:
If you perform the “ping” test please ensure that the firewall configuration of the PC is not blocking the test.
