using openvpn on linux

[lwkoon]

hi Reuben,

when i use linux issue "openvpn --config bolehroute.ovpn"

i got connected but it won't give me the routes
error:-
NOTE: unable to redirect default gateway -- Cannot read current default gateway from system

i have to manual add route to be able to ping 10.10.10.1

any automated way to workaround?

could you post the full log?

What flavour of linux are u using?

[lwkoon]

Using centos 5.4
console mode without GUI

initially what i wanted to do is NATing all the traffic via the linux router through ur OpenVPN channel, via tun0

my log will be

Hi,
1. have you done the ip forwarding?
2. Is your firewall/iptables/selinux enable? Please disable this.
3. Did you make any modification to the config file?
4. Please paste the config file you are using.

I sort this out once I get the info from you. BTW, is this local server or headless?

[lwkoon]

Nevermind, i have found a work around
the problem is the linux openvpn can't detect the ppp0 default route from linux.
just delete the default route and add 219.93.218.177 to the linux box
then start the openvpn, the openvpn will give u the routing that bolehvpn server has set.

Thanks lwkoon for updating us

might be in /etc/openvpn
