Running the server on an NAT firewall with no port forwardin

Let me guess.. Vicibox wont work if I use my netgear nighthawk mr5100 that has NAT firewall with no port forwarding?

Vicibox (and asterisk) works fine behind a NAT, port forwarding won't work for RTP (voice) packets as it chooses a different port each negotiation anyway. The only constant port will be your SIP port UDP 5060 (and web 80/4443/ssh 22), which if you are trying to access your box externally will need to be forwarded. There are a few NAT options you can try if things aren't working. https://www.voip-info.org/asterisk-sip-nat/

Actually I found a setting to set up port forwarding on the nighthawk...
Im not sure if I am doing this wrong or if its the nighthawk
