UDP Streaming with a router in the middle


#1

Hi,

How i can streaming in a UDP with a router in the middle, without using a VPN, only portforwarding between local, remote router, microPMU and PC. I used a VPN to connect LAN-LAN and use ipadress to connect directly microPMU to PC. But now i want to not use a VPN.

I am using NAT configuration to access microPMU on HTTP. But how datastreaming UDP? In microPMU which is the best “spot” to send data, router 1 or router 2?

I tried both, but the commands of configuration frame from microPMU to PC had destination unreachable. This happen because microPMU try to send package to a router and not to PC. PC is listenning on a port of router 1 or 2.

I don’t know if i explain well. Try with this.

Hi Aleixo,

  • The microPMU should be configured to send data to router 2’s WAN address.
  • Router 2 needs a NAT rule to forward data on UDP 4713 to the PC.
  • The PC should be configured to send data to router 1’s WAN address.
  • Router 1 needs a NAT rule to forward data on UDP 4713 to the microPMU.

Some of this configuration could potentially be simplified if the microPMU could stream unsolicited data and/or if it could send data using the same local endpoint as is used to receive commands. Unfortunately, I don’t think the microPMU can do either of those things.

Thanks,
Stephen

Thank you very much your answer Stephen.

With that kind of configuration, what could be configuration of PMU Connection tester?

  • UDP: Check
  • Local port: ?
  • Enable Multicast/Remote Udp: Check
  • Multicast Source: ?
  • Host IP: ?
  • Remote port: ?

Configuration alternate command channel?

I ask this because when i have a IP adress of PC or mPMU is easy to understand IP Host, but in this case i think we have a PC listen on Router2 but send command to Router1. I can not understand how receive in a specific location and transmit to other location.

Thank you for your attention to this
