====== NAT / PAT ======
  * Statički NAT
NAT s jedne unutarnje adrese na jednu vanjsku adresu

  ip nat inside source static x.x.x.x y.y.y.y !(adresa_iz_mreže   adresa_s_vanjske_strane)
  interface ser x/y
  ip nat inside
  interface ser z/w
  ip nat outside

  * Dinamički NAT

  ip nat pool IME_POOLA x.x.x.x y.y.y.y (range adrese) netmask m.m.m.m
  access-list 26 permit x.x.x.x w.w.w.w (hostovi kojima se izvršava NAT)
  ip nat inside source list 26 pool IME_POOLA
  interface ser x/y
  ip nat inside
  interface ser /w
  ip nat outside

  * Statički PAT

  access-list 38 permit x.x.x.x w.w.w.w !(host kojem se vrši PAT)
  ip nat inside source list 1 interface ser x/y overload !(serijski interface koji ima vanjsku adresu i na tu adresu se vrši NAT)
  interface ser x/y
  ip nat inside
  interface ser z/w
  ip nat outside

  * Dinamički PAT

  ip nat pool IME_POOLA x.x.x.x y.y.y.y (range adrese) netmask m.m.m.m 
  access-list 26 permit x.x.x.x w.w.w.w (hostovi kojima se izvršava NAT)
