NFS mounting from client pc

The server ip is 10.2.2.24. I have installed nfs-utils package the i have edited /etc/exports
i have added the following line
/home 10.2.2.0/24(rw,sync,no_root_squash,no_all_squash)
i have saved, i have started the nfs service, then i am trying to mount nfs sharing from client machine using the following command
mkdir /mnt/nfs
mount -t nfs 10.2.2.24:/home /mnt/nfs
but it is not mounting nfs sharing please guide me to rectify that
