Depends on what you mean.  iptables supports stateful firewalling, so if
RealPlayer is using something simple (afaik it uses standard UDP) then
iptables will be able to handle it.  If it didn't, you'd be SOL, since
the iptables folks have a policy of not supporting/building/including
in the kernel modules for protocols that do not have at least one Free
server and one Free client.
