Hi I am trying to connect to a vpn server (vpntunnel) from my dlink 323
i Installed openvpn thanks to
funpkg -i openvpn-2.2.1-2.tgz

I use this /ffp/etc/openvpn.conf (the same as the one I use on my personal computer)
float
client
dev tun
proto udp
nobind

; CERT
ca /ffp/etc/openvpn/cert/ca.crt
ns-cert-type server
cipher BF-CBC

; HOST
remote-random
remote anna.vpntunnel.se 10010
remote anna.vpntunnel.se 10020
remote anna.vpntunnel.se 1194

resolv-retry infinite

; AUTH
auth-user-pass
persist-key
persist-tun

comp-lzo
verb 1

when I connect openvpn I have
Starting /ffp/sbin/openvpn --persist-tun --persist-key --config /ffp/etc/openvpn.conf
