Hi Rohit, 

Thank your for your answer.
My tests were done without upgrading systemvmtemplates, and I have few more results :

1/ It fails for both old (created on 4.9.2) and new (created on 4.9.3) VPC
2/ It fails for old (4.9.2) and new (4.9.3) instances
3/ As long as the virtual routeur (created on 4.9.2) is not destroyed, static nat / port forwarding
is working
4/ Once a VR is re-created (or freshly created on 4.9.3), it stop working

>From what I can see. If no static nat nor port forward is set for an instance, the instance
can access Internet using the source-nat interface.
Once you assign a port-forward / static nat to a instance, you can no longer access the instance
from outside, and the instance itself can no longer access Internet (but is able to ping the

On the VR, the 3 interfaces are properly configured and within VR, no problem to ping Internet.

Anybody else can reproduce this issue ?

Hi Gregoire,

For 4.9, no systemvmtemplate upgrade is necessary. Please re-perform your tests without upgrading
systemvmtemplate and let us know what failed and what steps were performed, thanks.

Hi All,

Great job, thanks for this release.
I've made basic testing today ugrading 4.9.2 to 4.9.3.
Except VPC, my test were all successfull.

Is there a systemvm template upgrade to perform ? (I only found new templates for 4.10).

The main bug I found is related to iptable that stop allowing / forwarding traffic for instance
inside VPC.
The use case is :

- Upgrade mgmt from 4.9.2 to 4.9.3
- Check instances connectivity (inside vpc using PAT or static NAT) => OK
- Restart VPC with clean option (or destroy router and let mgmt create a new one)
- Check instancs connectivity (still both PAT /SNAT) => KO
- Try to assign another ACL (to be sure not the same as
=> still KO

If no systemvm template upgrade is required, I'll dig tomorrow this case, as it sounds a big
blocker to a production upgrade.
