I had a similar problem on my machine, but it had nothing to do with network manager. You might try verifying that firestarter (or other local firewall) is not blocking the traffic - not sure why, but it seems to limit outbound traffic on the tunnel interface. When pinging to the remote side, I got replies that looked like this: tsuther angrybutler999:~$ ping 200.200.203.232 PING 200.200.203.232 (200.200.203.232) 56(84) bytes of data. ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted ping: sendmsg: Operation not permitted --- 200.200.203.232 ping statistics --- 23 packets transmitted, 0 received, 100% packet loss, time 22084ms Hopefully that helps, Regards, Tom On Tue, 2008-03-18 at 15:17 +0100, Xin ZHOU wrote: > Hello, > > I'm new user of linux and I'm using Ubuntu 7.10. > > Followed by some tutorial on internet, I've installed > network-manager-vpnc and vpnc.
