[I] Port forwarding rules gets the same public port when creating port forwarding rules with CloudStack's API [cloudstack]
saffronjam opened a new issue, #8386:
URL: https://github.com/apache/cloudstack/issues/8386
##### ISSUE TYPE
* Bug Report
##### COMPONENT NAME
~~~
API for Virtual Router Port forwarding rules
~~~
##### CLOUDSTACK VERSION
~~~
4.18.1
~~~
##### CONFIGURATION
Isolated network Source NAT with redundant router
##### OS / ENVIRONMENT
Ubuntu 22.04
My client is the Go client for CloudStack's API
##### SUMMARY
Using the API I was able to create, what I think, is a race-condition for port forwarding rules that is not handled by the API. Two port forwarding rules ended up with the same public port, even though I should have received an error such as:
"The range specified, 2502-2502, conflicts with ... ".
##### STEPS TO REPRODUCE
~~~
Using the API create 2 port forwarding rules with same public port (for 2 different VMs in my case).
~~~
##### EXPECTED RESULTS
~~~
Conflict error, that I can handle in my client using the CloudStack API.
~~~
##### ACTUAL RESULTS
~~~
Two port forwarding rules created, with the same public port, for different VMs. Only one of them works of course.

Hi Daan,
Sorry about the delay. Right now, I am unable to replicate this, and it could have been caused by some bad state in the router maybe? I will reopen this issue if I am able to reliably replicate the issue.
As a solution on our side though, we added a Mongo database layer between, with a unique index, to ensure the port forwarding rules are unique.
You can probably close this issue for now.

@saffronjam do you have a script for this (code fragment?) and do you have a work around to get you going?
