  • Updated 2 years ago
I am operating from my Daughters house trying to use the my iPad and Iphone Smart SDR App .
Using Soft ether VPN I can connect to my home VPN set up , it works fine DIRECTLY from my iphone or iPad Pro using the VPN and using either my hotspot from Sprint or my hotspot from ATT connects perfect every time but when I try to use the WiFi at my daughters house it connects to my VPN no problem, shows the Flex 6300 on the screen trying to discover but Never connects. Only way to connect is through my hotspot. I had this issue a few other times from other WiFI connections remotely? SIgnal is strong and speed shows 10MB but wont connect to the radio ? Almost like the port is blocked here she is using COX Triple play TV phone and internet High speed. Any thoughts? Thanks. I have a fix through my hotspot but hate to use all my monthly data.My direct email is n2bj@comcast.net

Hi Barry, nice to see you in the flex world..

perhaps the remote network is using the same private IP range as the WIFI network you are on and the NAT is not working quite right?  A way to avoid that would be to turn your home network into a less likely used range, such as 10.X.X.X rather than the ubiquitously common 192.168.1.X to get a more consistent result.

Thanks for response Chris. This would be a multiple day job as it has taken forever to get all the cameras, security, repeaters and access points to work properly and honestly I am dangerous on network setting sharing etc. I am computer literate but shallownon complicated network settings and sharing. I have a work around using my 2 hotspots from my cellphones but even slowing the display it sucks up my data so quick . When I have a high speed cable modem with unlimited data and it's fast I am looking for a alternate fix.
I have been running remote for over 15 years using Skype and Remote Desktop or team viewer but having the Flex now and the Flex Remote app on my iPad and iPhone is unbelievable!

Thanks again 73 Merry Xmas and happy holidays to all Barry N2Bj

No problem Barry, once again its great to see another regular contester out here...  If you need any contest related setup assistance/station integration or whatever,  I have been working with the flex team for over a year on contest related issues and am part of the Alpha group.  Feel free to drop me an email direct if you need assistance in filling any of the functionality gaps.  73 OM.

I had that same problem. I could access my Flex from my Verizon network but when I switched my iPhone to the WiFi, it would see the Flex but I could not connect. I changed everything from 192.1.1.xxx to 192.10.1.xxx and everything started working again. That is great info and thank you for providing this information.

No, you must have each LAN IP subnet different for SmartSDR for IOS to see the radio. They cannot be the same. As Chris pointed out, I use a 10.x.x.x scheme to try and keep it different from off the shelf consumer routers.

I know it can be a laborious task to change your home network but you will be better off down the road.

If your daughter's house does not have anything that has a fixed IP address you can change her router to not conflict with your existing home subnet for now.

Hi, the Softether documentation acknowledges the IP subnet issue in what it calls "legacy VPN products" . It then goes on to describe how a Softether VPN overcomes this well established problem by establishing a layer 2 VPN.

https://www.softether.org/1-features/...

Barry, It may be worth looking at this (especially sections 2.3 - 2.5) as it would save you the aggravation of having to change one of your subnets. I have my Softether server configured in this way to include a local bridge and I have had no trouble connecting from a variety of locations with a variety of IP's. The client computer always obtains its IP from the DHCP server at the site of the VPN server so there is no conflict.

I hope this may be helpful.

This will not help him with SmartSDR for IOS.

Thanks Dave, not an expert here but hoped I'd stumbled into a potential solution. In my ignorance, I cant reall see why it wouldn't help if the remote client "thinks" it is connected directly to the lan where the radio resides. Please could you expand on why it wont work?

I think for it to work on same LAN subnets you need both SoftEther server (at home) and client (remote). I don't remember seeing a SoftEther client for iPad or iPhone.

Thanks Dave, fair point. In which case, rather than changing a subnet to get around the problem, it may be quicker & easier in some situations to set up a Softether client on a cheap widows tablet, laptop or Pi and connecting the iOS computer via that.

I recall this solution has been discussed in various threads, eg:

Thanks to all. I just want to point out the MY Softether is on a separate server it is on a Rasberry PI. Unfortunately I am not an expert on programming in the Rasberry Pi Language or at setting up bridges and VPN so I need all the help I can get. Now that I explained I have the VPN SoftEther on the Raspberry PI does anyone have a quick fix for me. Like stated if I use my Iphone either on Sprint or ATT with the Hotspot it works every time just sucks up all my DATA on my plan.Thanks again for everyones input just need a quick fix if possible.73 Barry N2BJ   n2bj@Comcast.net
