    Hello Guys
    i have to allow port 5060 UDP for SIP only from 1.1.1.1 (Sip provider Public IP) to my STATIC Public IP (PPPoE DSL connection from my ISP)  to reach Private 192.168.x..x PBX IP.
    Which NAT should i pick in this situation SOURCE,STATIC or DESTINATION NAT ?
    Thanks in advance :)

    Hello,


    Whenever you have a Public IP and you want port forwarding, you do destination natting.
    You specify the source IP to be 1.1.1.1 and port 5060 and then destination to be 192.168.x.x.
    There is tons of resources online for CLI and J-Web configurations for port forwarding

    As Hussam said, you just need destination nat as source IP will be not changed 

    check the below link for the needed sample configuration
