Zdrawej 
Taka e praw si za static nat stawa duma ili Source NAT (SNAT). 
Interfaceto sum go wdignal otdawna - inache wuobshte ne poteglia NAT-a 
Problema e kak da potegli trafika i wuw 2-rata posoka t.e. ot router-a

Triabwa li tam da polzwam DNAT ? t.e. da napisha obratnoto prawilo ili
samo SNAT-a e dostatuchen ?
