qvno stava vypros za edno i systo nesto, no ima edna kamara
imena/slovosy4etaniq kojto se sreshtat/polzvat. Pyk i gornite dve imena
mozhe pak da ne dadat qsnota, zastoto osven port(s) mozhe da se
forward-va/map-va i address(es) (ip). Za tova nqkoj go nari4at obsto IP Port
Forwarding ili samo Port Forwarding, ama ne e losho da se obqsni kvo to4no se
iska v zada4ata (kakto beshe obqsneno i beshe to4no otgovoreno). Mozhe da se
sreshne i kato NAT + Port Multiplexing (ili NAT + Port Forwarding), koeto
systo ne bi bilo pogreshno ponezhe v NAT RFC-to (1631) ne se spomenava nisto
za port-ove a samo za adresi a i se vizirashe samo Dynamic NAT (dokolkoto si
spomnqm).
Oba4e (za tozi slu4aj konkretno) , po-korektno bi bilo:
Static Destination Network Address and Port Translation.
(vsi4ko e qsno).
Mozhe da se sreshne i kato Inbound (IP/Port) Mapping.
("Inbound" ... ama idi gi razberi, 4e ide re4 za NAT ;)

mda, i az si mislq 4e userland-a dale4 ne e mnogo save kato mqsto za
