Hi

 

VPN PPTP work on the Phone

-- BUT --

If I enable Hotspot of S9 and i connect my PC to HotSpot of S9, I can't connect to a PPTP VPN.

 

This is a problem of soft. Maybe Ports are blocked or protocol GRE ? But there is really a problem !

 

EDIT : With Samsung S7 => It work ! It's really a problem of S9 ...

Cool, thanks! Will this work on the S9+?

Maybe in theory, but the direct link I provided on XDA were for the S9, so you will need to go to the firmware science main page and enter the build number for your device (in About>Software Information).  

 

Use the AT&T S9 Update site as a reference for the update path.

https://www.att.com/devicehowto/tutorial.html#!/stepbystep/id/stepbystep_KM1253489?make=Samsung&mode...

 

For the S9+ it goes:

1) G965USQU1ARB7

2) G965USQU1ARBI

3) G965USQS2ARF4

4) G965USQU3ARG7

5) G965USQS3ARG8 

 

You must update in this order.  If you are still on RB7, then you can probably just update to RBI and then the other updates will happen on their own (it might take a day or so to get fully updated automatically, but you should be able to get RF4 immediately after you update). 

 

Also, be aware that after the manual update, my phone was reset.  It wasn't a big deal because part of my troubleshooting to fix it not updating was to do a reset. 

 

After I got RG8 PPTP vpn worked on my hotspot.

Interesting, when checking the software update information, it states that im on version:G965U1UES2ARF4/G96U1OYM2ARF4/G965U1UES2ARF4.

 

Note: Just saw your reply.

In that case, I'd be hesitant to do the manual update (using the firmware science site, anyway) because they deviate from the AT&T update path.  If you enter RF4, they suggest an update to RF5, but AT&T went from RF4 ti RG7.

Thanks for the heads up. I'm going to backup my phone and start the updating process. I'm hoping this will take care of the issue. I currently have a tp-link VPN router at home, which when I activate VPN on my phone, it works for about a minute and boots me off. I use L2TP/IPSec pre shared key as my security; I also troubleshot this by using my buddies VPN (same setting/router) on my phone. Still drops. Furthermore, he has an iPhoneX and has no issues when connecting to his or my set up. :hand-with-index-and-middle-fingers-crossed:

No problem.  But you know the issue you're describing is a different issue than what is being discussed here, right?  I have no idea if the update to RG8 will help you, but I can confirm that RG8 fixes the issue where PPTP VPN connection fails from a computer that's using an S9 hotspot.

 

Anyway.  Good luck

Hello,

 

I received OTA base version G960FXXS2BRH8

I was disappointed to see that, using this new version,  Access through VPN was still not working.

Afterwards, I enabled manually in phone settings: "Mobile Hotspot Protected Management Frames"

Now I can connect to my VPN.

You can found this option in mobile hotspot advanced configuration.

Hope it will works for you too.
