If the network that the flex is on has a 192.168.1.x IP, then there could be a conflict. I would suggest renumbering the network since a lot of public and home wifi is 192.168.1.x. That is the most common problem.

Check what IP the radio has. Chances are if it's 192.168.1.x it will be in conflict with whatever remote network you are on.

You can also see the IP in the chooser. Hover over it and you'll see it in a black box.

The fact that you just got a new router makes this scenario I described extremely likely since the default setting for most of them is 192.168.1.x

The procedure to change the LAN IP network numbering varies with the router. If in doubt, ask a networking expert near you to help you...

Ria, Could he possibly VPN into his local network and change the settings on his router without locking himself completely out of the VPN after rebooting the router?

I'm not sufficiently experienced with Softether.net to know if the remote server management would allow him to make some changes before the reboot that would allow him back in....

Or perhaps using Parallels Access, which I DO have, and is not bound by the router's subnet problem, as far as I know.

Just a thought.

The best way to do it is to use TeamViewer which will automatically reestablish a connection.

OR he can open up the WAN side of his router and access admin through there but some routers disable that.

I might even offer to help him if he wanted. It won’t take me very long to do.

If you have 1 computer inside your network, then you can fix the rest, and it seems you can with TV.  Ria has a good offer here and I am sure if she takes her time, it might take 5 minutes.  :)

UPD 500 4500 and 1701 are for an L2TP VPN connection from IOS.  443 and 5555 are for Softether connections.

How are you connecting to the radio?  With the VPN active or not active.  Or, are you using SmartLink?

Are there port forwards on your router for 4991 and 4992?  You didn't say.

I am not able to do that as a Flex employee due to liability issues. Sorry. Someone else might be able to though.

It does sound like all your IP addresses changed with the new router. This is to be expected as normal operation.

There are solutions to prevent that from happening in the future when you plan out your network.

Doug, you are correct. The radio discovery is via UDP broadcast packets. It doesn't matter what subnet the radio is set to. SmartSDR will "see" the radio. However if it is not in the same subnet or somehow able to reach the network SmartSDR cannot establish a control connection which is via TCP.

Thanks everyone. I got everything working again. Not quite sure what I did, but sometimes that's the best way I guess. All OK now. Been working for the last few hours and working many European stations. Having a blast once again. I hope this doesn't happen again... at least not for a while.
