Port Forwarding to "reserved" IP?
Hi!
I want to configure a port forwarding rule to a reserved IP (Which is assigned as a virtual IP across several VMs). Using the Cloudstack load balancer is not what I want, as it appears as the source of every request in the application log files.
I have excluded a range of reserved IPs from the Network as described in http://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.2.0/html/Admin_Guide/reserved-ip-addresses-non-csvms.html
(I use Cloudstack 4.4.1, but the documentation appears to be still valid).
This IP is not "known" to Cloudstack, as it is not assigned to any VM. So I cannot choose "a VM to forward to", but I need to enter the IP directly. Via GUI this is not possible.
I tried it via Cloud Monkey:
> create portforwardingrule ipaddressid=589d1160-5618-452f-a78c-dfd6dbec5fb9 networkid=1b3893a0-367b-4805-974b-72ae735680fa privateport=8088 privateendport=8088 publicport=18088 publicendport=18088 protocol=tcp vmguestip=192.168.101.10
Missing arguments: virtualmachineid
Faking it by adding some innocent VM's UUID obviously does not work:

Error: IP Address is not in the VM nic's network
So I am stuck here... Any hint on how to make the port forwarding happen?
Thanks,
Martin

Thanks... That was my Plan B, but I thought there might be another way...
I'll try that out.
Ciao

Hi, Martin. CloudStack needs to know about the IP to be able to create a PF rule for it. One potential workaround I think might work would be to acquire a secondary IP for one of the VMs, use that for the virtual IP in your application, and configure the PF rule for it in CloudStack.
Best regards,
Kirk

Hi, Martin. CloudStack needs to know about the IP to be able to create

to acquire a secondary IP for one of the VMs, use that for the virtual
