Hi Mitch,
The TL-WR802 I don't think has a firewall as much when running in "client" mode as it basically just is a wireless to ethernet bridge.

The RRC is set to DHCP and the DHCP server is set to off, it simply passes everything through.
I agree with you that a bridge should normally not have a firewall if designed correctly, but I have seen some routers that were run in bridge mode indeed still had firewalls running. That is why I suggested that you double-check it. The problem you described is typical for firewalls.

Hard to say, but make sure that the TL-WR802 has its firewall turned off and SIP ALG is also not
enabled. If it allows your PC to access the WiFi, then it should work on your RRC as well.

I also assumed that your RRC is set to DHCP and the TL-WR802's DHCP server is turned off.

Hi Jens,

I guess that is a "nein". This is covered in the manual on pages 11 & 12, but I can send you
my networking checklist that walks you through the procedure if you want.

Du kannst mir eine kurze Mail an dj0qn (at) darc.de senden und ich kann die Checkliste an dich weiterleiten.

Jens,

Did you forward the correct ports in your router and change the SIP contact to the external IP address
or DynamicDNS address?

Paul,

Using VPN with an RRC is somewhat difficult to use when traveling to a hotel. There are ways
to get it working, but some normal users may struggle to get it working. It may or may not
solve this issue in the future for this type of problem.

I doubt that it is blocked somewhere in the internet. If blocked anywhere, it is in that hotel's
router or their ISP. That is correct about having them forward those ports (UDP) in their
router.

I guess that Mike at Microbit will have to get back to you on this one. I am just a normal user and
have limited test ability, mainly TS-480 and K3.

Honestly, I believe that this problem is therefore caused by the iPhone. It is blocking packets it does
not like. The question is, why? Maybe you can Google to see if there are problems in general with the
iPhone hotspot blocking types of packets.

Somehow that is exactly what I expected to happen. I am not sure what the problem is
with that router, but that is where your problem lies.

The data requirements are 100% not the issue. Look at COM0's data rate of 57600 bps. That
is a small part of your available bandwidth, even on the uplink side.

What I suspect is the router's firewall sees something in the datastream it doesn't like and is
blocking it. See if a firewall in the router is turned on. If you can turn it off, that should solve the
problem. Also make sure that SIP ALG is deactivated.

Right, that is exactly what I suspect. He will have to have the admin enter port forward or
some other method to allow him to access. It is a rare problem in hotels, but I have experienced
it as well.

We shall see what their answer is.

Hi Paul,

I didn't have much time before I ran out to explain my last question -- basically if an RRC works at one
location (or, like in your case, others do as well), then does not work when one moves it, then the
problem is that there is a problem with the control RRC's network. This is rare and is usually found with
business routers at companies and sometimes in a hotel. In these cases, routers need to get tweaked if
possible. That is why I asked if he can get router access or at least have an admin do something.

One other thing popped-up in my head while I was out: did he change his RRC to DHCP? If it was set to
a fixed IP at his home, then that would possibly explain his problem. If so, all he needs to do is to use the
Microbit Setup Manager and a USB cable (maybe also network will work if lucky) to set the RRC to DHCP.
I usually assume that people run their control RRC's under DHCP, but some people don't and are surprised
when it doesn't work when they do go somewhere else.

Does he have access to the router where he is?

Paul,

What does the status page of his and the radio RRC say when he tries to make a connect?
You can perhaps locate the problem there.

Are you using port 5060 for SIP?

No, the data rate of 57600 baud is identical to the TS-480 and should certainly be no more complex.
Certainly, 57.6k bps out of a modern broadband line is insignificant and any amount of overhead on
top would be in the couple k bps area and will have zero effect.

I will anxiously await the results of your test and dream about a solution tonight  ;)

Ok, I think I got it now, but this just doesn't make any sense. If I can summarize:

- You verified that the ports work fine, since these same ports work for the TS-480 that didn't for the V71A
- Since the ports work fine, it is not a router problem
- You verified that it is not a specific RRC problem, swapping RRC's has the same problem with the V71A
- The V71A works fine within the LAN
- There is no error code, but no audio passes when outside of the LAN

This is very strange. There is no reason why changing the rig for another one would make
any difference, since you verified that it works in the LAN. The rig has no influence over the
way it works over the internet using a pair of RRC's.

I will have to sleep on this one, but there is no logical explanation for your problem. Maybe we need to
think out of the box on this. See if you can take your V71A control RRC to another location and use someone
else's internet to try to access it. Maybe the problem is in your control RRC's router, or the interface between
the rig to the control RRC and the router. At least that is the only thing left that hasn't been looked at (I think).

To allow VOX to work with any rig under RemoteRig, you must change under advanced settings
the "RTP tx mode" to "continuous" on both RRC's.

Configuration, RRC 1258 / Re: No access to Control RRC

The RRC's themselves do not support IPv6. If you can reach the network from the outside and
route to an internal IPv4 number, it would work, but not as a standard IPv6 device.
