Conventional IP network - no audio

[adfire]

Hello,

Does anyone know what TCP/UDP ports should be open between repeaters in a conv. IP network if there is a router with firewall between them ?

I'm trying to set it up, but I think there is a problem with network - when I transmit through one repeater, on the other one the diode is blinking green, and I see strong signal strength. But I can hear nothing...

The same pair of repeaters in a lab were working great. The lab was identical, meaning IP addressing, but there was no firewall, and NAT. And now it doesn't work, but there is a router between them with quite complicated config. But I can ping both of them, remotely connect via programming software and so on.

What other thing may be wrong if not unavailable some open ports ? (what ports ?)

Thanks in advance
Mike

You need to figure out what ports are being used by the repeaters and make sure they are open in the router. If those ports are closed, you won't get it to work.

You have to use a vpn between sites, or wide area LAN. Due to the sip nature one can't just hook up the kti-3 to the internet and just go. The udp ports get lost in the scheme of things.

see nxdninfo.com on my ham project.

Not sure, depends on the product. But it sounds to me as if you've got them open as when you "key" one repeater, you can see activity on the other one.

Now I know everything. Because there's a network address translation between the repeaters, and voice needs high udp ports, they are lost in the scheme of things as kd4efm said. I will reconfigure the network, and I'm sure everything will be ok.
I have a list of all needed tcp/udp ports to be open in that scenario if someone is interested.
Thanks for all your help.

AGAIN, I will tell you this AGAIN, as I have been there DONE THAT.

YOU HAVE TO USE VPN SITE TO SITE WITH KENWOOD and the KTI-3. PERIOD.
Beat your head all you want. 64000 and 64001 with NAT and or Port Forwarding WONT WORK.

UNDERSTAND? Open the ports, and you still have NOTHING. Tried that, owned up to that.

I am not blowing wind to blow wind. I spent 6 months trying to circumvent this and LOST OUT. The ONE
and ONLY WAY it will work is VPN site to site. I have multiple customers using NXDN IP site to site
using LAN over wide area, and it works fine. but ONLY IN THE SAME 10.x.x.x NETWORK.
10.x.x.x, 172.16.x.x, 192.168.x.x, if it is not in the same network, it wont work. The packets are
very structured. Any off line packet received by the NXR-??? will be garbage. You get PTT, great,
but your not going to get voice.

I'm not going to argue, but I'm telling you, there is another way to make it work. It all depends of a network scheme, way of connection between two nodes. I've had two NXRs' in my lab, using router, connected each of them to a WAN interface, and it has worked...
Tommorow I'll do what I have to do with the network, and we'll see. I'll let you know.
And don't be so nervous

Ok. You are absolutely right. Because I'm more IT than radiocommunication specialist, I have tried everything. I understand the problem, but don't understand why preserving outgoing udp ports in NAT, and binding them to the same incoming ports (I use that trick quite often), it still doesn't work. I also don't understand, why it has worked in my lab, where the repeaters were in a different IP subnets, connected through WAN interfaces. This config is almost the same as now..
It was very instructive lesson for me, thanks kd4efm.
Finally all the repetaters are in the same subnet, but I know what to do in the future, when it won't be possible.

I burned that fire long time ago, Glad it was a learning curve for you. With the NXref, and I by NO MEANS
created the program, but aided a fellow ham in Atlanta who wrote the code, we surpassed the 16 site limit
of the pre-version 2.0 of NXR-x10 series.We still have an Icom and Kenwood tied back to back "bridge"
and the Icom uses the single port reflector while the kenwood uses two ports, C&C and data.
Yes the embeded UDP gets FLIPPED any way you probe it. From what I was told, that is part of the
security of just hooking up the KTI-3 and let it rip. Also why the code is this small, it does not do DNS.
That's why Kenwood and I went round and round... (yes I met some harsh words 6 years ago)
For Ham radio, this project was submitted to Kenwood and to Icom for approval. Yet they won't give
us true code blessings, they do allow us to experiment with what we have done, and they watch us
in good detail. As you may now know, I think Alinco?? now has a NXDN CAI radio
(I hear about it, have not seen it yet but was said to have been seen at the Shelby NC ham-fest).

We have an extensive group of Railroad Radio tech on the NE Corridor who have put some good
time into the northern network on my yahoo group. just look for HAM_NXDN and leave me a note.
Would like to have a few more techies join and work on advancing our cause.

Cheers
