In the latest DD-WRT builds, for me this means no more having to put in the Startup script:

Code:
openvpn --mktun --dev tap0
brctl addif br0 tap0
ifconfig tap0 0.0.0.0 promisc up


and no more Firewall script either:

Code:
iptables -I INPUT -p udp --dport 1194 -j ACCEPT


Everything just works now from the improved GUI and is very simple...

Is it possible to configure DD-WRT to act as an OpenVPN CLIENT at this time?

Assuming you already have an active OpenVPN SERVER configured and operational?

Hi Smile
I have a couple of questions about this :

1) if I want to channel all my LAN traffic through the VPN, the Daemon mode must be used and not the client mode?
2) there's no rules at all in the management console, the GUI takes all in charge?

on Arethusa site, they give the following instructions :

Go to Administration -> Commands.

Enter these 3 lines in "Commands":
iptables -I FORWARD -i br0 -o tun0 -j ACCEPT
iptables -I FORWARD -i tun0 -o br0 -j ACCEPT
iptables -A POSTROUTING -t nat -o tun0 -j MASQUERADE

Click on "Save Firewall".

dear op,

can you post a client config file that works with your GUI setup on post#1?
At my wits end here. TIA

I too am having terrible luck getting a client config file to work with the settings mentioned by the OP.

Anybody have any luck with this configuration and willing to post up a copy of their client config file? Obviously after you remove/change sensitive info.

Thanks.

Just to clarify, this documentation is "AS IS" and is only an indication as to "what to-do" when setting up OpenVPN on newer releases of dd-wrt.

Remember, that Server Settings must be used on client side!

Example: LZO Compression server side = Yes
Then Client side = LZO Compression = Yes.

Enable client to client, if you need clients to see eachother, and remember that the VPN Ip scope must be able to handle the amount of clients.

Server Config:

If your setup is running, and suddenly stops, after changing some settings. Use SSH to the router and look at the log file, for errors as these might not be shown on the WebGUI

Sometimes, the apply settings, messes up keys/certificates and nothing shows on Status page, try re-applying the keys and reload.
