Hello, I am trying to configure a VPN so that I can access my home network from work and vice versa as well as the fact that I am just curious. So, I have DD-WRT installed on my Buffalo WRZ-300n-hp router and have been trying to get this configured via various how tos here and at the DD-WRT site. I think that I have followed most recipes to the T but am still not connecting and I am a novice and don't know how to trouble shoot this config. So any help would be appreciated.

----Server config-----
Note that I don't have any firewall configuration and that I have forwarded port 1194 from the gateway to the VPN network.

----OpenVPN status from the router page------

----The client config is as follows-----

client
dev tun
proto udp
remote mydns_hostname 1194
resolv-retry infinite
nobind
persist-key
persist-tun
ca ca.crt
cert client1.crt
key client1.key
ns-cert-type server
cipher BF-CBC 128
comp-lzo
verb 3

-----Client log is-------

From this link http://www.dd-wrt.com/wiki/index.php/OpenVPN is written that "Start type" must be "WAN up", because "System" mode does not work.

Thanks Mimiko, I have tried both start on WanUp and System...neither are working for me. I do have it set to WanUp now and will keep it there until I resolve this.. Thanks again
