Hi all. I have an OpenVPN server: 2.2.1-1 x86_64 Server config: port 11223 dev tap proto udp tls-server ca keys/ca.crt cert keys/server.crt key keys/server.key dh keys/dh1024.pem server 1.2.3.3 255.255.255.0 push "route 192.168.0.0 255.255.255.0 1.2.3.4" keepalive 10 60 client-to-client duplicate-cn inactive 600 log /var/log/openvpn.log syslog status /var/log/openvpn-status.log user openvpn group openvpn persist-tun persist-key verb 4 comp-lzo Server interface: 11: tap0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 100 link/ether 56:73:e7:c9:c8:e5 brd ff:ff:ff:ff:ff:ff inet 1.2.3.4/24 brd 1.2.3.255 scope global tap0 Client: 2.2.1-8ubuntu1 x86_64 Client config: remote 1.2.3.3 port 11223 dev tap proto udp resolv-retry infinite #nobind persist-key persist-tun tls-client ca /etc/openvpn/keys/ca.crt cert /etc/openvpn/keys/client.crt key /etc/openvpn/keys/client.key ns-cert-type server comp-lzo verb 4 log /var/log/openvpn.log #syslog status /var/log/openvpn-status.log After successful start of openvpn service (Tue Aug 21 16:12:24 2012 us=644993 Initialization Sequence Completed in logfile) I have: Client interface: 9: tap0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 100 link/ether 4a:3d:52:dc:51:c3 brd ff:ff:ff:ff:ff:ff When I start the tunnel I am not able to ping 1.2.3.4 IP on server, the TAP interface is also in DOWN state. I have no firewall configured. My client log file is attached. Should I have an IP addres on my TAP interface? Thanks for the help ;) Best regards, Rafal.
