Hi! Thanks for the hint, after creating an otherwise identical offering but with conserve mode on, I was able to configure the portforwarding. But it did not work yet. After creating one more offering, but with VirtualRouter instead of Ovs for Port Forwarding, the port forwarding finally works.
So thank you very much for saving my weekend so far ;) But I wonder: - why do I have to enable conserve mode (which as far as I understand just defers configuring the GRE tunnels and starting the virtual router until the first instance needs them)? - Why won't the portforwarding work with the Ovs provider? I followed this documentation: http://docs.cloudstack.apache.org/en/latest/networking/ovs-plugin.html which instructed me to use Ovs. - the GRE tunnels still use my storage network instead of the configured guest network on my xenservers (I wrote an email to the list yesterday regarding that) Any Ideas?

If yes can you check whether the conserver mode is set to "Yes" in your network offering? -Sanjeev -----Original Message----- From: Martin Emrich [mailto:martin.emr...@empolis.com] Sent: Thursday, October 30, 2014 6:26 PM To: users@cloudstack.apache.org Subject: The IP is already used as SourceNat rather than PortForwarding Hi! I created an isolated network (with GRE) on Cloudstack 4.4.1. Then I tried to configure a port forwarding rule for SSH to an instance. But I get an error message "is already used as SourceNat rather than PortForwarding". What am I doing wrong? Thanks Martin
