issue with Block connections without VPN - Samsung Galaxy S8 Questions and Answers

Hi guys,
i would like to use the option Block connections without VPN on my Galaxy S8 but it doesn't work well.
When i use it with the wi-fi there is no problem but when i turn it off and use the mobile data i just can't get any connection, my VPN disconnect and i can't reconnect it
My model is the SM-G950FD,
i'm on 8.0 last build on stock (CRC7),
my VPN is NordVPN (paid version) app up to date
hope you guys have a solution to my problem or at best if you know if it's from android or from the VPN provider (will ask them too)
thank's a lot

Good question. I have the same problem. "Block connections without VPN" should be renamed to "Block connections with or without VPN".
But i do connect initially, and then I'm blocked within 24 hours.

How to trigger VPN connection?

Hi,
So I have VPN settings configured as part of my "Work network".
I need it to be connected from time to time so the Wizard will reach servers at my office.
Is there a simple (or any) way to trigger the VPN to connect and stay connected until I ask to disconnect it?
Thanks,
Hello,
From looking at screenshots of how the built-in VPN client works, apparently when you click the connectivity icon, if you have a VPN configured, there should be another line with a link to connect to your VPN. I'm assuming this is how the VPN gets enabled. However, I am having a (possibly) similar issue with my Cingular 8125. Basically no matter what I do, that line never appears, and if I explicity try to connect to the VPN (Start -> Settings -> Connections -> Edit My VPN Servers -> (Tap and Hold on VPN Server) -> Connect), I get no indication either way that anything happened. Hopefully someone who has found a fix to this problem can shed some light on this issue.

Keep VPN connection alive?

Hello,
I'm using my TyTn on our wifi network, for which it requires a VPN connection as well. Everything works BUT... only the applications "Internet Explorer" and "Messaging" will cause the VPN connection to be made. The other applications don't. If the VPN connection is inactive for 30s, it closes down.
I can use other applications over this connection (Skype, MSN, Opera, ...) when I first launch PIE or Messaging. But oddly enough, the VPN connection is closed after 30s, even if there is an application using it. The solution would be to keep PIE or Messaging active.
I found commercial applications to keep a gprs connection alive, but would they work for the VPN connection (I don't know if pinging a server will keep the VPN alive)?
Any suggestions?
Thanks!

I don't know although I am currently looking into this matter, to keep vpn from shutting down ! Vpn by anchor Inc has not open to prevent standby and causes a network error when it stops working, it's been a few years or so since you posted this thread and no one has replied except me so I suggest that this is a task to difficult for anyone on xda to solve. :crying:

VPN via 3G/HSDPA is still unresolved ?

Hi Everyone,
Having the Shift as my workhorse since some moths, there is still one annoyance I couldn't avoid: my VPN connections are interrupting the Internet connection when using 3G/HSDPA modem connecting to Internet in Vista/WM.
I was trying to search through all existing threads, but I still don't see anyone finding a solution.
I think the root lays in WM somewhere, since I cannot establish a PPTP connection in WM neither. In my case it is certainly not caused by the data provider, because I have checked it with them.
Let's try to put our knowledge together to sort this out !
This is normal behaviour I suppose
When connected to the VPN, the VPN must provide you with either a proxy or another internet gateway, otherwise you are just connected to a private network...
Maybe you mean something else, but from what I read it seems like you never got on the internet with VPN active.
If you did, and you are talking about intermittent network errors, then only high performance settings on your power settings may help.
If you could give more info I could help more. IP/Proxy/Gateway/ did it ever work yes no etc.

Lucid,
Thanks for replying. I will try to explain it another way.
1. When I am connected to Internet via Wifi, I have no problem using my VPN connection. I get authenticated and connected to the company network and the connection stays active as long as I want.
2. Using 3G/HSDPA Internet, the following happens:
- I start the same VPN connection, and get connected.
- Than my 3G/HSDPA connection breaks up, and the PPTP dialin stays alive - it doesn't have any use this way of course.
- When I disconnect from VPN, the 3G connection comes back automatically.
I hope this is more clear this way, any hints are very welcome !

Thats exactly the same problem that i have had for over months - it just doesn't work and I can't see any way to get it to work - so much so, I don't use the Shift anymore - got a Tytn II and redfly and just remote desktop to a PC on the work lan!

The VPN that you are running is on VISTA side.(if yes try to see the routing table) by default the VPN get the default GW, and try to change it.
If this is the issue then you can go to the VPN connection properties -> Networking ->TCP/IP -> Properties -> Advanced -> IP Setings -> unchek the use the default GW on remote network.
regards
Is this a problem caused by this vista "feature", which disconnects the 3G Modem from Vista, as soon as an other network is being connected via WLan or via cable?
I think this is a stupid feature. Instead of that the users just should set the metrics for the networks manually and you can be sure, that Vista always uses the WLAN instead of the GSM/3G modem, if both where available.

alazarid,
Thanks a ton, the TCP/IP part did the trick ! Now my VPN has a use ).
cheers !
Ok guys heres the issue...
At first I thought this problem was associated with the fact that there may have been some software monitoring for other data connections, to disable the GSM modem when not needed...
After checking into everything, I found that there is probably NO software that does this...
Since WM handles the passthrough for the 3G connection, and ontop of that the actual endpoint for the data connection on the GSM connection is the WM side and not Vista, what happens is what when the VPN creates a connection and you opt-in to use the default remote gateway (I prefer to use it, because I require this for the work I do), the default gateway is updated on the 3G network interface.
I beleive that this update of configuration, then causes the WM side to stop the connection because either a) it doesn't know howto interprit this or b) retries to create the connection because it thinks there is an error.
I havn't played with this for a few weeks, and have my fair shareof other stuff I deal with, so I cannot remember if WM NATs the 3G connection, but the key thing breaking this is the WM side.
I beleive that IF you did want to hack up a configuration that uses the remote gateway, you could configure a VPN connection under Windows Mobile and have WM connect to the VPN, therefor the PC would be using that connection (but wouldn't be aware that its connected to the VPN), therefore giving the user access to the VPN, WITH the remote default gateway being used.
Again, as I mentioned its been a while since ive gone tech on my Shift, but I beleive this is correct. If anyone wants to add anything, please feel free.

VPN Connection PPTP disconnect

hi all,
I want to use PPTP vpn connection to my work
The PPTP vpn connection is established successfully.
However if I switch to an application which would generate internet traffic (such as internet explorer) my PPTP connection drops.
What is the problem ?
thanks
That's normal. Happens to me everytime. When you access your providers' ISP through updating weather, stocks or starting IE, it will boot your VPN connection. For me, it is do to my service provider.
so there is nothing to do to resolve this issue ? i would like to use VPN access to my work to check email with Internet Explorer ..
You need to add work network exceptions to force required types of traffic to go through the VPN tunnel. Plenty of relevant discussions around, just google it. Here's a link to one particular overview:

VPN Pptp over wifi in HTC Leo

Hi!
I have been trying to connect to my to vpn pptp server (witopia.net) for 2 days. I tried every combination that i could think, but there must be something i am doing wrong. I think the mobile is trying to connect to the vpn server through gsm because everytime i try to connect the gsm signal bars disappear for a few moments. How can i make sure that the vpn connection goes through wifi?
I have managed to actually connect to the vpn server, but i cannot access websites like facebook and youtube from the Leo (I live in China and they are blocked). I am able to access blocked services through my iphone and laptop through the same vpn connection.
Any suggestions?
Thanks
PPTP on WM6 is a major problem. Especially if the server (and most do) required MPPE. Its one of the few niggles I have about WM. If you own the server your best setting up the conection using L2TP/IPSEC.
Or if you dont own the VPN server, and have a server laying around the house (as I do) you could set up your server to use the PPTP VPN then set there server as a Proxy, and connect WM6 to the server via proxy...so basically WM6>Proxy>VPN>interwebs
Hi Jagnet, Thank you for your reply.
Unfortunately i am not able to use Ipsec/L2TP in China, only PPTP works fine with blocked sites.
After trying many combinations, there is a step that i havent been able to figure it out.
Once i am in Start > Settings > Connections (tab) > Connections (icon) > Advanced (tab) > Select Networks, How do i select the WIFI connection in "Programs that automatically connect to the internet should connect using" opcion? . On the modem tab i only can choose "celullar line", "Celullar line (GPRS)" or "Hayes Compatible on COM1:", there is nothing about WIFI there, so when i try to connect at the vpn server specified in "Programs that automatically connect to a private network should connect using", the phone seems to be trying to connect via GPRS.
¿Any ideas?
Thanks

having similar issues with HD2. CMCC as well, in China.
I am getting a proxy IP address if I check on ipchicken.com, etc
but I am not able to open FB.
I am not using the PPTP option, but using their SSL service with
openVPN. but STILL not working..
right now on support chats with witopia.
VPN PPTP is simply broken in WM. It will work, but only with no encryption at all, which beats the purpose.
First of all sorry for bumping this old thread. But I have been looking and it seems kinda close to what I`m doing, oh a little new to vpn.
I have managed to sucessfully connect the HD2 via VPN in connections only when on the lan (outwith I need to contact O2 to get it enabled apparently). I setup a dialup connection in Win 7; HD2 says I`m connected to the VPN.
However heres the thing. Am I right in thinking that folders by default have to be shared. Therefore when using resco I can see network folders anyway, when connected to wifi.
So how would I prove that I can see folders shared to the VPN and not on the LAN as I cant seem to prove whether I`m seeing the folder via LAN and not on the VPN?
Sorry if its confusing but perhaps you get my drift? Or am I missing the point entirely....
