Iptables port forwarding for specific host dd-wrt/tomato

i m trying to open ports 5060 and 5004 (udp & tcp) for a specific internal ip (192.168.1.5) but i only want communication over these ports to be between specific external host(s) and deny everything else to this internal IP. i have tried various rules but they either seem to open port for any external source or block everything. Here is my -vL output
