Gillingham will host one of their largest away followings of the season when Dover visit in the FA Cup first round on Saturday.
The non-league side will be backed by almost 2,500 supporters when they make the short trip to Priestfield.
"We want to put a performance on for the supporters and to make sure they go home proud of their side," said Martin Hayes, the Dover manager.
"The support we have is phenomenal for a small non-league club and we'll have around a third of the gate. We just want to give them something to cheer."
