Only one way video and audio transmission with HDX 8000

I have HDX 8000 behind the SonicWall TZ215 firewall, and with the port forwarding configuration, I was able to reach the unit (that has only private IP) from outside. However, there is no audio or sound that reaches the other side.

 

Researching the past forum logs I got an impression that it was the NAT issue, but I don't know what to do from here. Here are what I tried:

1. open all the possible ports on SonicWall for outgoing traffic from this HDX 8000

2. Turn off Windows Firewall on RealPresence laptop

3. Check the router/modem that Spectrum provided. However, they would not give me a direct access, so I could only ask question to the tech support. but it is in Bridge mode, and there is no port blocking.

4. Check the packet monitor on the SonicWall firewall. No dropped traffic from this HDX 8000

5. Put HDX 8000 outside the firewall, and gave it a public IP (yet still no image/sound transmitted to RealPresense)

 

Lastly, we tried to use it via site-to-site VPN a year ago, and I think it stopped working at one point.

 

So is the problem at:

a. modem/router where HDX 8000 is connected to?

b. RealPresense setting?

c. Router that RealPresense laptop is connected?

Hello @Stingray,

welcome back to the Polycom Community.

It is always useful to include the currently used Software version as issues experienced or a question asked may already be addressed in a newer release.

In addition some or a couple of your old post(s) => here <= are still open / pending as you have not marked these as "Accept as a solution" or at least provided some form of feedback or answer.

Could you therefore kindly go over them and mark or answer as appropriate ?

If they are marked as "Accept as a solution" other users can find these easier and it helps them to utilise the community more efficiently.
