I use the following script to set things up -

#! /bin/bash
# commonly used IPs and aliases
. /root/iptables/env

# Set up Port Forwarding for VNC
/sbin/iptables -t nat -A PREROUTING -p tcp -i ${EXTERNAL_INTERFACE} -s ${WORK_IP} --dport 5900 -j DNAT --to ${HOME_IP}:5900
/sbin/iptables -I block 1           -p tcp -i ${EXTERNAL_INTERFACE} -s ${WORK_IP} --dport 5900 -d ${HOME_IP} -j ACCEPT
