Openvpn and gsm data

raduspl

Openvpn server (type TLS), Nexus 5, OTA-8 (16.04).
I can go vpn online only via wifi, via gsm data only allows you to establish a vpn connection to the server and go to the tun0 network.
Server configuration is correct - other Android devices are working correctly.
Many thanks for any help!

Error net::ERR_NAME_RESOLUTION_FAILED

Do you use lzo compression ? i suspect without lzo compression its not working ... but need confirmation!

raduspl

Yes, I use lzo

Can yoi try with an other server with udp protocol ?

I have two private vpn servers based on ubuntu openvpn software just as configured (I suppose).
The problem concerns only one of them located outside of my country.
Both use lzo, udp, TLS and ta.key.

Don't think a can help you more sorry

@rasduspl There are two VPN tutorials in here https://forums.ubports.com/topic/2008/the-ubports-tutorial-links-collection that might help.

Additional options:

push “dhcp-option DNS 208.67.222.222”
push “dhcp-option DNS 208.67.220.220”

in the server configuration solved the problem.
Thx
