I Have a D Link Router and Need to Carry Out Port Forwarding?

I am using Optus dial up broadband and it linked to D! 624S taht connects to a VOIP modem. I need to port forward following ports.

1. SIP ports 5060 through 5061 using UDP protocol
2. TFTP port 69 using UDP protocol
3. DNS port 53 using UDP protocol
4. RTP ports 1638 through 32767 using UDP protocol
5. UDP Port 10000 to 19999

As advised by the VOIP provider there is a need to specify two port ranges to be opened as follows:

1. 5060 - 5061 (UDP)
2. 16384-32767 (UDP)

I am now only able to rcv incoming but cannot make calls out.

Pse advise how to resolve this as I am stuck.

Cheers
