kiranchavala opened a new issue, #14146:
URL: https://github.com/apache/cloudstack/issues/14146

   ### problem
   
   CreatePortForwardingRuleCmd on a VPC tier doesn't trigger ipassoc ( firewall 
and   conserve mode on in vpc offering)

   
   ### versions
   
   ACS 4.23
   
   ### The steps to reproduce the bug
   
   4.23 introduced the conserve mode and firewall feature in vpc 
   
   
https://docs.cloudstack.apache.org/en/4.23.0.0/adminguide/networking/virtual_private_cloud_config.html
   
   1. Create a vpc offering with firewall service and conserve mode enabled 
   2. Launch a vpc network with the vpc offering 
   3. Acquire a public ip 
   4. Create a  firewall rule 
   5. Create a tier and launch a vm in the tier 
   6. Create a PF rule on the same public ip to the vm 
   7. Try to ssh to the vm on port 22 > ssh fails 
   8. Login to the router and found that the public ip is not associated with 
the eth1 interface

   ### What to do about it?
   
   Workaround 
   
   Restart the vpc with cleanup; applies  the rule correctly  and the user is 
able to ssh 
   
   User should be able to ssh when there is firewall and PF rule present in the 
vpc
