CertWays Q: 3 SIMULATION
The CertWays network is displayed below:
CertWays.com is in the process of updating their network. They're going to change their internet service
provider, install a local E-mail server, and install Microsoft Exchange Server 2003. The new ISP has
allocated CertWays.com a new Class C address range. However, the addresses of the internal routers and
servers are to be kept intact. So you are to configure the router for NAT so the internal clients can use a
single external IP address assigned to the public router interface. Finally you want Microsoft Exchange
Server 2003 to be Internet accessible, so you have to provide a static translation for it.
Your task is to configure the router for this using the following information:
CertWaysNAT
S0: 192.168.212.1/24
E0: 10.30.50.1/24
Secret password: CertWays















Answer:
CertWaysNAT# config t
CertWaysNAT(config)# access-list 5 permit 10.30.50.0 0.0.0.255
CertWaysNAT(config)# ip nat inside source list5 interface s0 overload
CertWaysNAT(config)# ip nat inside source static 10.30.50.5 192.168.212.5
CertWaysNAT(config)# int s 0
CertWaysNAT(config-if)# ip nat outside
CertWaysNAT(config-if)# exit
CertWaysNAT(config)# int e 0
CertWaysNAT(config-if)# ip nat inside
CertWaysNAT(config-if)# <Ctrl-Z>
CertWaysNAT# copy running start
CertWaysNAT#

Incorrect Answer:

CertWaysNAT# config t
CertWaysNAT(config)# access-list 5 permit 10.30.50.0 0.0.0.255
CertWaysNAT(config)# ip nat pool lan 192.168.212.1 192.168.212.1 netmask 255.255.255.0
CertWaysNAT(config)# ip nat inside source list 5 pool lan overload
CertWaysNAT(config)# ip nat inside source static 10.30.50.5 192.168.212.5
CertWaysNAT(config)# int s 0
CertWaysNAT(config-if)# ip nat outside
CertWaysNAT(config-if)# exit
CertWaysNAT(config)# int e 0
CertWaysNAT(config-if)# ip nat inside
CertWaysNAT(config-if)# <Ctrl-Z>
CertWaysNAT# copy running start
CertWaysNAT#
