The only goal of the game at the Bangor Fuels Arena came on 63 minutes as Walsh got on the end of a cross from Dominic Melly and it was enough to see the Championship One side through to the next round where they face Queen's University at The Dub on Saturday, 1 March.
Jonathan Parr was forced to keep out a goalbound effort from Jordan Forsythe on 19 minutes as Gareth Scates' side made an encouraging start to the tie.
Another chance fell to Stephen O'Neill, but he failed to hit the target.
Striker Daniel Hughes responded for the visitors forcing goalkeeper Paul Cairnduff to make a fine save at the second attempt.
In the second half, Cairnduff was forced to retire through injury with Darren Gibbons taking his place on the hour mark.
Three minutes later and the deadlock was broken by Walsh and Bangor could have doubled their lead near the end when Ethan Boylan was denied by Parr.
Ballinamallard's Irish Cup tie against Glenavon at Ferney Park lasted only 32 minutes before being abandoned.
A torrential downpour started at the beginning of the tie and as the water began to lie on the pitch referee Mervyn Smyth had no option but to bring proceedings to a halt for player safety.
Glenavon had missed a penalty after Shane McCabe was fouled in the box, but Brian McCaul's spot kick hit the woodwork.
A date to play the tie at the third attempt is expected to be on Saturday, 1 March, but is yet to be confirmed.
Earlier in the day Glentoran's replay against Armagh City was also beaten by the elements as The Oval failed a 1.30pm inspection. They will try again on the first Saturday of March.
