NAT problems and solutions...

[pd0swl]

Sorry to flood the forum with my NAT problems.

If you read:
http://www.smartvox.co.uk/sipfaq_natsolutions_explained.htm
One sulotion could be to let the RRCs do continuous handshaking even if the radio/controlpanel are off.

Since NAT is becoming more and more widespread, would Microbit consider this or another NAT workaround?

I can't see that any changes are needed, we support all kind of routers already.

But there are lot of bad routers out there, specially those which are sent out from the ISP free of charge. Many of them don't support port forwarding in a proper way. Use the world wide known brands Netgear, Linksys or D-link then everything works.

But there are also ISP that restrict you to only use their (NAT) modem, otherwise they place you out of their service. I think this problem may grow in the future.

The above article describes the NAT/ SIP problem often encountered these days.

I'll see if another modem is an option with my ISP.
Suggestions of type welcome.

Another problem Mikael, is that more and more people are having a "package deal" with ISPs for both internet and VOIP telephony via 1 modem. At least here in NL.

In this case you are forced to use the ISP delivered modem, since the VOIP part is locked.
If you change modem, you loose telephony.
Behind such a modem, Remoterig will have problems.

In my specific case, the NAT ports are dropped after the first working contact.
A continuous handshaking between RRCs might work around in these cases I think.
If I leave my radio on, the line is not dropped.

Just  for your consideration.

*If* my RRC system works, it works absolutely great btw...
