@tamoorahmedntu I am not sure whether I understood the issue you are facing but I believe you may be able to report the issue better after going through this document: https://docs.cloudstack.apache.org/en/latest/adminguide/systemvm.html#accessing-system-vms.

The issue I'm facing is the Web console to CPVM is only accessible once I ssh into it and tell iptables to allow all ports. I'm sure this is not correct I should not be sshing into the vm and allowing all ports in order for the console to work.

@tamoorahmedntu
can you share the output of some commands inside CPVM ?

• iptables-save
• ip a
• ip route

[tamoorahmedntu]

Unfortunately I'm unable to that until I solve another issue #9489

@tamoorahmedntu I suspect the issue is possibly caused by the same subnet in the management/pod and public traffic. Is it possible to use two different subnets for them?
