Currently running OpenWRT 10.03.1 Luci on my WNDR3700v2 and working flawlessly.
I also have setup an OpenVPN connection and working ok, iptables and routing also working.

The main thing is that I have to start OpenVPN every time the router starts with this command: openvpn --cd /etc/openvpn --config ovpn140.ovpn

I have tried some scripts and played with the S95done and S95openvpn. The problem is that if it starts, not sure if it do, there's no internet connetion
I remove all the scripts and lines, reboot router and start with the command, everything is ok.

Is it possible to run the command after 2 min or etc. when the router is finally booted and WAN is up?

Conclusion, I just want OpenVPN to start when the router is up and have WAN IP and finished with the booting

Maybe you need hotplug? If I'm not mistaking, there can be a script in /etc/hotplug/iface or in /etc/hotplug/net which is executed when the interface is taken up. Consult here.

Thanks, looks like /etc/hotplug.d/iface should be my right place since the DDNS is in that folder (25-ddns).
So the 25-ddns file looks like this:

#!/bin/sh

. /usr/lib/ddns/dynamic_dns_functions.sh

if [ "$ACTION" = "ifup" ]; then
        start_daemon_for_all_ddns_sections "$INTERFACE"
fi

If I create a file with name "30-openvpn", how can I make a script to run the openvpn like in my first post?
Writing scripts is not normally for me

I think something like this sould work

#!/bin/sh

if [ "$ACTION" = "ifup" && "$INTERFACE"="<name of your wan interface, i.e. ppp0 or 3g-wan or ...>" ]; then
        openvpn --cd /etc/openvpn --config ovpn140.ovpn &
fi

What about just using /etc/config/openvpn ?

Here's my settings in beginning of it:

config 'openvpn' 'custom_config'
        option 'config' '/etc/openvpn/my-vpn.conf'

Then I replace my-vpn.conf to ovpn140.conf
and then add the line "option enabled 1"?

Yes. But that'll obviously only work if the openvpn init script is still the original one.

No problem, the script is set back to it's original and I will test

But, should i delete rest of the lines in the /etc/config/openvpn file?

You can delete it, yes. But the rest is disabled by default anyway, so it won't interfere.

Hmm...that trick did not the work. It's not starting the OpenVPN and there is no OpenVPN process running.
Did I miss something?

If your config is indeed failing without "--cd /etc/openvpn" you have to add "option cd /etc/openvpn" as well.

Tried that, without luck. Here's my config:

Maybe I have to delete the other config anyway so it just run the custom config?

Edit: My ovpn140 file suppose to be ovpn160 from the beginning.

Alleb57, can you confirm if that script will work or not?
The second trick I got in this thread did not work for me

This automatically starts openvpn at boot for me, added the following line to file: /etc/rc.local (LuCi local startup file)

openvpn /etc/config/openvpn &

The ampersand is required.

What's the problem, just use it and see whether it works or not

robrob, I tried that earlier, but did not work. The router is starting up, but no VPN process is running

I also tried with the suggestion from Alleb57, without success:

#!/bin/sh

if [ "$ACTION" = "ifup" && "$INTERFACE"="pppoe-wan" ]; then
        openvpn --cd /etc/openvpn --config ovpn160.ovpn &
fi

Not sure why nothing works, I'll bet I have to check some logs or make a cronjob after 2 min the router is up.
This automatically start stuff works in DD-WRT, but may take up to 2 min after WAN is up before it's trying to reconnect.

Is there possible to add a line with "wait 1 min" after the interface is up?

Try adding debug info to the script, something like

#!/bin/sh
logger -t test ACTION="$ACTION", INTERFACE="$INTERFACE"

if [ "$ACTION" = "ifup" && "$INTERFACE"="pppoe-wan" ]; then
        logger -t test Trying to start openvpn
        openvpn --cd /etc/openvpn --config ovpn160.ovpn &
fi

If you need to wait, try adding
sleep 120
before starting openvpn

I wonder why you even need to sync your openvpn startup to the wan state, usually the process just tries to reach its peer indefinitely, so there's no need to wait until wan is up.

If the current openvpn config includes a resolv-retry parameter, make sure its set to "infinite" or remove it entirely. Also add "verb 5" to increase the log level and add "syslog"
to make openvpn send all its info to logread.

jow, here's the VPN settings I have:

remote 123.456.789.123 4672
proto udp
ca ca.crt
cert ovpn160.crt
key ovpn160.key
tls-auth ta.key 1
client
dev tun
resolv-retry infinite
nobind
persist-key
persist-tun
;http-proxy-retry # retry on connection failures
;http-proxy [proxy server] [proxy port #]
verb 4
mute 5
tun-mtu 1500
route-method exe
route-delay 2
comp-lzo adaptive
explicit-exit-notify 2
fragment  1390
mssfix 1390

I will add the logging and see what's going on

The problem is fixed

Just edited the rc.local file with the sleep command.

Thanks folks!
