The Mariners booked a place in the Conference promotion final at Wembley against Bristol Rovers after comfortably beating Eastleigh.
Eastleigh created the better of the early chances, but Ollie Palmer's sharp turn and shot extended Town's 2-1 aggregate lead from the first leg.
Having set up the opener, Lenell John-Lewis then added a second with a cool right-footed finish before the break.
Eastleigh pushed forward but struggled to create chances, before Palmer slotted home a third to seal the win.
The result meant that Town kept alive their hopes of returning to the Football League for the first time since their relegation from League Two in 2010.
Earlier in the day, Bristol Rovers eased into the promotion final with a 3-0 aggregate victory over Forest Green.
