Abstract
Razvojem Interneta i TCP/IP komunikacijskog modela omogućeno je slanje podataka s jednog kraja mreže na drugi IPv4 adresiranjem. Zbog naglog rasta Interneta, slobodnih IPv4 adresa za dodjelu više nema. Unatoč tome, danas se i dalje, najviše koriste IPv4 adrese zbog implementacije NAT tehnologije, odnosno prevođenja mrežnih adresa. NAT zamjena izvorišne ili odredišne IP adrese omogućuje lokalnim mrežama primjenu privatnog skupa IP adresa za internu komunikaciju te javnog skupa IP adresa za eksternu komunikaciju. Prema dostupnoj literaturi, objašnjen je rad nekoliko vrsta NAT tehnologija te način njihove implementacije, nazivlje vezano za NAT i njegove prednosti i nedostaci. Simulacijom i testiranjem dinamičkog i statičkog NAT-a na pravoj opremi potvrđen je literaturni dio rada. U radu su u testnoj mreži statički mapirane tri javne IP adrese s tri lokalne IP adrese primjenom MikroTik usmjerivača. Dinamičkim mapiranjem povezana je jedna javna IP podmreža s jednom lokalnom podmrežom primjenom NAT pravila u MikroTik usmjerivaču.

Parallel abstract (English)
The development of the Internet and of the TCP/IP communication model made end-toend network communication possible using IPv4 addressing. Due to the rapid growth of the Internet, now there are no more free unallocated unique IPv4 addresses. Nevertheless, today these IPv4 addresses are still the most used ones due to the implementation of NAT technology, i.e. network address translation. By replacing the source or destination IP address NAT allows the local networks the application of the private set of IP addresses for internal communication and public set of IP addresses for external communication. According to the available literature, the operation of several types of NAT technologies has been explained as well as the methods of implementation, terminology related to NAT and its advantages and disadvantages. By simulating and testing of dynamic and static NAT on the right equipment the literature part of the paper has been confirmed. In the paper three public IP addresses with the three local IP addresses have been statically mapped in the test network using the MikroTik router. By dynamic mapping one public IP subnets has been connected to one local subnet using the NAT rules in the MikroTik router.
