Steve Morison ran the show as Millwall overcame Middlesbrough for the first time since 1992 with a 2-1 win.
The Lions, who needed extra time to sneak past Wycombe in the first round, won a penalty on 28 minutes after Tarmo Kink brought Alan Dunne down in the area.
Morison, who completed his lightning-quick rise from non- League to international football when he won his first cap for Wales two weeks ago, duly slotted from the spot to put his team ahead.
Liam Trotter doubled the advantage five minutes before half-time when he was set up for a close-range finish by Paul Robinson. Boro improved after the break and pulled a goal back through Scott McDonald in the 89th minute.

Mor like it, Lions
Millwall grabbed a first win over Boro in 18 years thanks to Steve Morison and Liam Trotter.
Two first-half goals did the trick - although Scott McDonald's late chip gave the hosts a nervous finish.
Den chief Kenny Jackett said: "It was hard-earned, Boro are a good side. We were at full stretch."
Striker Morison gave Jackett's side a 28th-minute lead from the spot, making it three goals in his last three games.
Boro striker Tarmo Kink clumsily felled Millwall winger Danny Schofield to concede the penalty.
Nine minutes later the visitors failed to deal with James Henry's corner and Trotter rifled the ball into the net.
But a howler by keeper David Forde gifted Boro a goal as he left McDonald's shot and saw it sneak under the crossbar.
Middlesbrough boss Gordon Strachan said: "That hurts, but I can walk away with my head held high because the players gave everything."

Strachan unhappy with referee
Gordon Strachan last night questioned the penalty decision made by referee Graham Horwood that proved the turning point in Middlesbrough's Carling Cup exit at Millwall.
Strachan was frustrated by the way Horwood chose to go with his assistant's flag, which was raised when Tarmo Kink appeared to shove full-back Alan Dunne to the floor just before the half hour, rather than make the decision himself.
The Boro boss walked off the New Den pitch with the officials at full-time, questioning why the penalty was awarded in that manner.
It was not that he disagreed with the controversial spotkick, which was scored by Steve Morison, just that he felt the man in the middle should have awarded it.
"It's not a complaint. I get paid more money than my backroom staff to make tough decisions, I don't send my backroom staff in to tell a young player he is leaving on a free," said Strachan.
"I do it. The referee gets paid more than the linesman so I think there was lack of responsibility from the referee to go with the linesman.
I tell my players that they must take responsibility.
That's what the referee should have done.
The result hurts but if you give it your best shot then that hurts. It's when you have let people down when it is hard to live with."
Middlesbrough were then left two behind when Liam Trotter added a second six minutes before half-time, which left Middlesbrough effectively out of the Carling Cup despite Scott McDonald's late consolation.
"It was a smashing game of football and I am pleased with the part we played in after Sunday's match with Sheffield United," he said. I will sleep better tonight after Sunday, which was not a good game and we didn't play well. We still want to enjoy our football and I would like to see improvement, but all in all we moved the ball well."
