4. Summary • High school • The assignment • Lower level applications and techniques • Advanced web application • Conclusion • Questions?

5. The assignment • CCNA lab's • Router simulators • Remote lab network security • Practice at home using an advanced web application

6. The assignment • Lower level applications and techniques • Tom Bosch • Telnet session with routers • Virtual computer and remote desktop • Web application • Robin Njotea • PHP with MySQL database

7. The assignment Network topography:

8. The assignment • Inside dotted line: Lab topography • Outside dotted line: Administrative network • Async module: Translation telnet - serial connection

9. Summary • High school • The assignment • Lower level applications and techniques • Advanced web application • Conclusion • Questions?

10. Lower level techniques • Network Address Translation (NAT) • Translate internal IP address to external IP address and visa versa • Disadvantage: As much external IP addresses as internal IP addresses needed

11. Lower level techniques • Port Address Translation (PAT) • Translate several internal IP addresses to one external IP address with different port number • Advantage: Use one external IP address for several internal IP addresses

12. Lower level techniques • Telent session (Async) • Start-up with empty routers • Batch file: • Move log file • Reload router script • Remove “old” static translation from router • Generate random port number • Add “new” static translation

13. Summary • High school • The assignment • Lower level applications and techniques • Advanced web application • Conclusion • Questions?

14. Advanced web application • Student login • View a CCNP lab  Advanced routers  Pix

15. Advanced web application • Reservation  Different lab’s different reservation pages • Insert reservation in a database • Holding time  Carry out batch files

16. Advanced web application

17. Advanced web application • Carry out lab  Get reservation information from database • Which lab which application • Batch files  Log each session  Reload each application for reuse

18. Advanced web application

19. Summary • High school • The assignment • Lower level applications and techniques • Advanced web application • Conclusion • Questions?

20. Conclusion • Research different aspects • Keeping it simple makes it harder • 2 large parts: • Lower level applications and techniques • Advanced web application • Bring these parts back together
