I just noticed that my Android (running CM11) is not correctly routing my traffic to my openvpn server. I noticed when I was looking at the current connections on my OpenWRT router that I could see the VPN's local IP address, and the remote connection! It looks like this:

IPV4    TCP 157.166.xx.xx:80

I could see all this in Luci's connection graphs, which means that OpenVPN is not sending my traffic over the tunnel at all, despite the reports from sites like ipleak.net . This means that when I connect over mobile data, my carrier can likely see all of my traffic. This is not what I want, I am having a hard time fixing it.

I tried two different OpenVPN frontends, tweaking the firewall on the phone (afwall+) and also playing around with the 'redirect-gateway' directives. I am not sure if this a DNS leak or total disobiedience on Android's part of my routing rules. The fact that I can see these connections from the router makes me think that the traffic is not even being encrypted before it's sent over the internet. Any ideas or advice?

Server Config:

mode server
local x.x.x.x
port 35777
proto udp
dev tun0
ca /etc/openvpnca.crt
cert /etc/openvpn/randomcn.crt
key /etc/openvpn/randomcn.key
dh /etc/openvpn/dh.pem
topology p2p
;topology subnet

ifconfig-pool-persist ipp.txt
client-config-dir clients
keepalive 7 80
tls-auth /etc/openvpn/ta.key 0
cipher AES-128-CBC
max-clients 3
user nobody
group nogroup
status openvpn-status.log

log openvpn.log

In my client directory, I have these settings. On my PC I do not have this IP leak problem despite the settings being the same:

push "redirect-gateway def1 bypass-dhcp"
push "dhcp-option DNS"

I have dnscrypt running with unbound on the server, serving the clients. This configuration works on my PC, but it seems no matter what I do I still can see the vpn local IP and all of my remote connections with Luci on openwrt.

I have tried using both OpenVPN connect, Openvpn for Android, and I am currently trying to use the ICS binary as well. Any help would be appreciated.

After a lot of research, I realized that either my ROM was corrupt or infected with malware, so I started from scratch, factory wiped my phone and installed a new ROM. The problem has been resolved. You should never be able to see openvpn connections on the local network. If you are, chances are that something is wrong. Since it is so easy to simply reflash a phone, I figured I may as well take this opportunity to upgrade to lollipop.
