I suspect a network problem between hosts on port 1701 but I don't see any outgoing attempts any directions via tcpdump on port 1701. I'll play around a bit more. If anyone has any ideas, welcome :) Regards Tamas Monos DDI +44(0)2034687012 Chief Technical Office +44(0)2034687000 Veber: The Hosting Specialists Fax +44(0)871 522 7057 http://www.veber.co.uk Follow us on Twitter: www.twitter.com/veberhost Follow us on Facebook: www.facebook.com/veberhost -----Original Message----- From: Tamas Monos [mailto:tam...@veber.co.uk] Sent: 25 May 2012 12:13 To: cloudstack-users@incubator.apache.org Subject: VPN with CS 3.0.2 Hi, I have tried a few times with earlier version to setup VPN. I can get the tunnel up and see the ESP packets back and forth but I get no IP from the virtual router (tunnel endpoint) so I can't send any traffic through the tunnel. Any suggestions what I'm missing here?
