VPN PPTP ANDROID

RouterOS General
1

hi


Scenario 1;
Refer to the http://forum.mikrotik.com/t/android-2-2-pptp-mikrotik/47755/1
My case is almost similar with it.
My Samsung (android OS) cant connect to the VPN pptp as created. But all my pc/notebook and iphone work wells.


including
/ppp profile add local-address=PPTP-pool name=pptp-test remote-address=PPTP-pool use-encryption=required /ppp secret set phtan profile=pptp-test

If that does not help, then test after this:
/interface pptp-server server set mtu=1400 mru=1400


please help,
i had done alot of configuration, yet it still not working.

I think you will need to investigate the log output on the server, and/or packet sniff the traffic to figure out why it isn’t working, but Samsung Android in general does interoperate with the RouterOS pptp implementation. I have it working with my Samsung devices.

PPTP is insecure STOP USING IT!!!

Despite the fact PPTP is not recommended due to security reasons, sometime it is useful due to its simplicity.

I tried to configure it and it works with my android phone (Xiaomi running Miui 9.5 which is based on Android 6.0.1) without any issue:

/ip pool add name=pool-pptp ranges=192.168.101.10-192.168.101.250
/ppp profile add dns-server=1.1.1.1 local-address=192.168.101.1 name=profile-pptp remote-address=pool-pptp use-encryption=yes
/ppp secret add name=launtel password=fastly profile=profile-pptp service=pptp

/interface pptp-server server set authentication=pap,chap,mschap1,mschap2 default-profile=profile-pptp enabled=yes
/ip firewall filter
   add action=accept chain=input comment="Allow PPTP VPN" dst-port=1723 protocol=tcp
   add action=accept chain=input comment="Allow PPTP VPN" protocol=gre

On my phone, I didn’t set anything special - just type of VPN, username and password. Only caveat might be the encryption: With ****

use-encryption=yes

I can either enable or disable the PPP encryption in android. With

use-encryption=yes

I can use VPN only with disabled PPP encryption in android. With

use-encryption=required

I can use VPN only with enabled PPP encryption in android.

Since we don’t know what setting you use, neither what does your log say, this is the best I can do. As said earlier, it would be good to have some log info. For example like this:

/system logging action add name=vpnlog target=memory
/system logging add action=vpnlog topics=pptp
