NS5GT ADSL port forwarding for VOIP

[GadTan]

Hi all,

I have NS5GT ADSL installed and I connected one VOIP box.  However, due to firewall, the VOIP box need to open UDP 2000 and UDP 4000 for control and RTP.

I am the first time user of Juniper and I read whatever document I can find but I am still confused.  I would like to use WEB UI to do the port forwarding.

VOIP Box (IP 192.168.0.65) ––>NS5GT ADSL (Public IP, dynamic or static) -------> Internet

So I need to do port forwarding from Public IP to internal IP 192.168.0.65

Can someone help me to do the setup in WEB UI?

Appreciate your helps.

Thanks

Gad

If you only have 1 public IP, you have to use vip. Define a vip same as untrust on your untrust interface, create the service redirection you need (it seems that you have to enable vip multi port in your case #set vip mutli)
After that, create required rules from untrust to trust any VIP(1) needed_services
