Day 18 Lab 1 – Static NAT

Topology

 Instructions

Connect two routers together with a serial or crossover cable:

1. Add IP addresses to the routers and a Loopback interface on Router A, according to the diagram; the 172 network can use the default subnet mask
2. Designate NAT inside and outside interfaces
3. Add a static route on Router B to send all traffic back to Router A
4. Ping between Router A and Router B to test the serial line (remember clock rates)
5. Create a static NAT for 172.16.1.1 to 10.1.1.1 and turn on NAT debugging
6. Do an extended ping source from Loopback 0
7. Check the NAT translation table

Solution Hints and Commands

• ip nat inside command and ip nat outside command on the interfaces
• ip route global configuration command to add static route
• Static NAT: ip nat inside source static x.x.x.x  y.y.y.y command
• show ip nat translations command to check the NAT translation table
