Today’s video is about NAT ( Network Address Translation).
NAT in which a private IP address is mapped to a public IP address, where the public address is always the same IP address.
Static NAT creates a fixed translation of private addresses to public addresses, the main difference between dynamic NAT and Static NAT is that the static NAT allows a remote host to initiate a connection to a translated host if an access list exists that allows it, while dynamic NAT does not.
Dynamic network address translation Dynamic NAT is a technique in which multiple public internet protocol (IP) addresses are mapped and used with an internal private IP address.
Now
We want to configure a static NAT to the PC-1 of 192.168.1.2 so it can reach the servers on the internet.
On Router1
# int s0/0/0
# ip nat outside
# int g0/0
# ip nat inside.
# ip nat inside source static 192.168.1.2 10.1.1.11
Run this command:
# show ip nat translations
Now, ping the server.
# ping 8.8.8.8
Now we will configure dynamic NAT on the Router, to allow the network of 192.168.2.0 to access the internet.
Let us ping the default gateway.
# ping 192.168.2.1
Let us run a ping from a PC to the DNS server.
# ping 8.8.8.8
Let us configure dynamic NAT on the Router.
# int s0/0/0
# ip nat outside
# int g0/0
# ip nat inside
Now configuring an access list for the network
# access-list 1 permit 192.168.2.0 0.0.0.255
# ip nat pool NAT 10.1.1.5 10.1.1.10 netmask 255.255.255.0
# ip nat inside source list 1 pool NAT

Now, let us create NAT overloading or PAT.
Here we will have these two PCs to be nated to the IP address of the router.
On Router1
# int s0/0/0
# ip nat outside
# int g0/0
# ip nat inside
# ip nat inside source list 1 interface s0/0/0 overload
# access-list 1 permit 192.168.1.0 0.0.0.255
Let us enable telnet on Router2
# line vty 0 4
# login
# password cisco
# enable password cisco
Let us telnet to the router from one of the PCs.
Then run the command :
# show ip nat translations.
