iptables modifications never require a reboot. Read the man page for
iptables, which is quite complete.

A bit of warning: when modifying iptables, you need to be very careful
that you don't wipe-out any rules that allow you to gain remote access
to the server. For instance, if you have a default rule to DROP all
packets and an exception that allows port 22 (ssh) traffic, then
flushing all the rules in a table can make it impossible for you to
revert the change without remote-rebooting (or, worse yet, paying
someone to walk into the cage and push the reset button).

Remember to add that to your permanent configuration to be reloaded
after reboot.
