Leiston are through to the FA Cup first round for the first time ever after beating Lewes 3-1 away in Tuesday's fourth qualifying round replay.
Stuart Boardley scored twice and Luke Eagle netted the other goal as the Ridgeons League side stunned their Blue Square Premier opponents in Sussex.
"It's brilliant, we did change things and that worked a treat," Leiston boss Carl Chenery told BBC Radio Suffolk.
They now face Lancashire's Fleetwood at home on Saturday, 8 November.
The Leiston boss now feels confident they can make a solid cup run.
"Why not? We've got a decent draw to be fair, we're at home and Fleetwood aren't doing so well, so there's a chance. That's what cup football is all about.
"It's brilliant for everyone in the town."
A win in the first round will bring in �20,000 to the club and the chance to face Football League opposition.
