Connecting Windows to Ubuntu 12.04 openvpn

BrianBlaze

Hello beautiful people!

I have a VPN setup on my ubuntu server:

port 1194
proto tcp
dev tun
ca ca.crt
cert blaze-ubuntu.crt
key blaze-ubuntu.key
dh dh1024.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist ipp.txt
keepalive 10 120
comp-lzo
persist-key
persist-tun
status openvpn-status.log
verb 3
;mute 20

when I connect from my windows box I get this:

The problem is that I can ping the tun0 interface from Windows but my internet is not going through the VPN!

As you can see I have no default gateway on my VPN interface... I have been searching everywhere and can't find the answer to my problems... I want to be able to connect to my vpn and have the internet go through it. PLEASE HELP!

Thanks

i answered your OTHER post 2 minutes ago....

i am not sure if i should try to help you out because i (and most mods here)
confuse people with our answers...

i will try to help you though...

where is your client config?

if you want to redirect ALL traffic through vpn you need the redirect-gateway directive
on your server config...

Client config:

#                                            #
# This configuration can be used by multiple #
# clients, however each client should have   #
# its own cert and key files.                #
#                                            #

# will be pulling certain config file directives

# To use this feature, you will need to generate

I am a noob with openvpn and I appreciate your help 🙂

and when you ask "if you want to redirect ALL traffic through vpn you need the redirect-gateway directive
on your server config..."

That's exactly what I want to do but I don't know what you mean lol

krzee

you must have missed the rules above

**Post your configs from client and server, without comments. you can strip comments in linux/bsd with something like this:
 grep -vE '^#|^;|^$' server.conf

nobody wants to read 100 lines of crap comments for 15 lines of actual config options
please read and follow the rules, it will make your experience getting help that much easier for you

Kudos, krzee - I was going to post exactly what you did.

and when you ask "if you want to redirect ALL traffic through vpn you need the redirect-gateway directive
on your server config..."

That's exactly what I want to do but I don't know what you mean lol

add to your server config

push "redirect-gateway def1"

also check the docs section for related examples..
