I have an openvpn server set up on a raspberrypi 3 and the openvpn app on android.

 

I can use openvpn fine on mobile data, and have used it on private wifi connections fine. What I am struggling with is getting it to work on Spark free wifi. It seems to connect/authenticate fine, but I cannot do anything from there. Nothing will load in browsers/facebook/email etc etc. Yet when I use the Astrill app, I can use their vpn services fine.

 

Any ideas as to how/why I cannot get my own VPN to work, yet it works fine with Astrill?

Is astril openvpn as well or pptp/l2tp?

 

I've got an l2tp vpn at home and never noticed any issues on spark wifi.  You might be able to spin up a pretty quick pptp install at home (it's not the most secure though) and see if that works.....maybe just openvpn is blocked somehow.

Is there an IP conflict occurring between what Spark are allocating and your local network?

@davidcole - The Astrill app uses openweb and stealthvpn. I think openweb is a proxy?? and stealthvpn is their openvpn + extra meddling to make it work in China etc. I have not yet had a chance to test Astrill openvpn files in the openvpn for Android client while connected to Spark wifi.

 

 

 

@sbiddle - I am pretty sure it is not an ip conflict (my first thought), as when I connect without the VPN I am assigned in the 172.* range, and my VPN is assigning in the 10.0.8* range.

In an attempt to block spammers, Spark have possibly closed a port or port range that your private server runs on. That might be worth a look.

I've used OpenVPN and Cisco over Spark Free Wifi many times. Cisco used UDP 10000 from memory and OpenVPN was on the standard port. But have used various high ports.

 

Where is your VPN endpoint? Have you tried doing a traceroute to it and make sure it's nothing else in the way?

I am hosting it at home, and it worked fine over mobile data at the same, ie working on mobile data, turned it off, connected to Spark Wifi not working, then back to mobile data and working again. All within 30seconds or so of eachother. I have not tried a traceroute, I am using a ddns service and from memory it resolved it to the same ip when on mobile data.

So probably not a port issue then. Try pinging google DNS or a similar ip when connected via spark wifi. If you get a response but no web url's loading there may be an issue with your DNS servers, albeit strange that the issue is isolated to the wifi.
