if you want to connect to a vnc server on the vpn network over the vpn connection, then no, the vnc port does not have to be open on the firewall between the internet and the network
of course it does have to be open on the host where the vnc server resides

Thanks Sameh, for your attention. VNC is a
client/server program that allows a computer to be
controlled remotely by another computer by mouse and
keyboard. Normally, VNC works without any
complications on the local LAN. However, if I want to
control the computer being blocked by a firewall over
the internet (controlling an office computer from
home, for example), one way is to connect both home
and office first as clients to a virtual private
network, and then  control the office computer from
home using VNC. In my initial tests, though, it seems
I can't do this if the vnc port is blocked despite the
firewall rules: iptables -A INPUT -i tun+ j ACCEPT and
iptables -A FORWARD -i tun+ j ACCEPT.
