|McGoldrick 45, Murphy 63||Venue: Portman Road
DAVID McGoldrick and Daryl Murphy punished Millwall for some wasteful finishing as the Lions' miserable run of results at Portman Road continued.
The visitors missed a host of guilt-edged opportunities in front of goal before McGoldrick broke the deadlock in first-half stoppage time.
Murphy bundled home a corner after the restart to make the game safe and the Lions were unable to reply in a very one-sided second half.
Millwall had lost their previous two matches at Ipswich by a 3-0 scoreline.
After losing Lee Martin to a training-ground knee ligament injury, boss Ian Holloway elected to draft Jermaine Easter into his starting line up.
Loanee Mathias Ranegie was also included in the Millwall XI, replacing Ricardo Fuller as the sole striker in attack.
The Lions started on the front foot and should have been ahead after eight minutes.
Scott McDonald picked out the overlapping run of Scott Malone who found Martyn Woolford inside the box, only for Dean Gerken to keep out his toe-poke.
But the ball rebounded to Easter and his snapshot crashed off the underside of the crossbar, with Gerken stranded, before the hosts scrambled the ball away.
Easter's 20-yard drive was held by Ipswich's goalkeeper before Malone's chipped cross was headed wide by Ranegie as the Lions spurned several promising openings.
Paul Anderson registered the Blues' first meaningful shot on target in the 29th minute when he hooked a volley towards goal, but David Forde held on.
Anderson went close again, this time from range, five minutes later, but Millwall once again failed to capitalise on a glorious chance at the other end.
Ranegie won back possession in midfield, drove forward and played a perfectly-weighted pass into the feet of Woolford, who was bursting into the area.
But the winger took an uncharacteristically heavy touch and, sensing the ball getting away from him, swung a boot at the ball, slicing it into the side netting.
Forde had to be at full stretch to claw away Daryl Murphy's downward header in the 42nd minute but the Lions stopper was soon picking the ball out of his net.
McGoldrick seized upon a hopeful clearance up field, exchanged passes with Teddy Bishop and rifled into the far corner, via a slight deflection.
At the break, Holloway withdrew Jack Powell and brought on Magaye Gueye in the hope the winger could get the visitors back into the game.
But Millwall were sluggish in the second period and never looked like drawing level as Ipswich, spurred on by their goal, went in search of a second.
And they got it in the 63rd minute when Murphy stabbed home from three yards after the Lions failed to clear a corner into their box.
McDonald went close to pulling one back in the 66th minute but his curling 20-yard free-kick was tipped over the bar by Gerken's one-handed save.
Alan Dunne's optimistic 30-yard drive was also dealt with by the Ipswich keeper.
McGoldrick should have made it 3-0 when he collected Murphy's knock-down inside the area but the striker snatched at the chance and fired wide.
The hosts then shut up shop, and though McDonald did his best to keep the game alive with a weaving run and shot, which drifted wide, the Lions were well-beaten.
