openvpn - no upload when routing all traffic through VPN
Posted: Sat Nov 14, 2015 11:10 pm
Hi,
I've had an issue for the last few days which is simply driving me nuts - hope someone here can shed some light.
Current setup: openvpn server running on a synology NAS behind a small SOHO router - and 3 clients, one android media player (minix neo x8h-plus), one macbook (using tunnelblick), one ipad.
exactly the same .ovpn profile exported to all 3 clients, everything works perfect when not routing traffic through the VPN. There are some services for which I need to use the server's external IP address, so I added 'push "redirect-gateway def1"' ' to the openvpn.conf file on the server. I had no dns, so I also added 'push "dhcp-option DNS 8.8.8.8"' to the server config. No change done to the clients' config files.
Everything still works as designed on the macbook and the ipad, however - the android device is not able to upload. general web browsing is fine, but random generic speedtests on the internet always come back with 0 upload on the android (same tests give similar results on the other 2 devices, and even download speed on the android is similar to the others). google play market also does not work when connected to the vpn, and a number of different services (streaming, for example).
I tried to disable the redirect from the server and add it to the local config file on the android - same issue. problem does not replicate on any of the other 2 devices.
same android media player works fine when connected to another openvpn server (again, with the redirect-gateway option enabled).
I have tried another openvpn client (random free client from the market) - same behaviour.
anyone, any idea what could be causing this? I would really appreciate some help...
