Hi Jeroen,

Fair enough – happy to stand corrected if this is the case. If you can trace 
this back to a specific XS patch could you log a Jira ticket for it and provide 
details?

Subject: AW: Firewall on xenserver

Hi Dag,

I've spent the last weeks doing some testing with CS4.9 and Xen 6.5 and I did 
not have this issue before.
Only the last two tests (yesterday and last week) this behaviour popped up, 
both with clean Xen installations.

Looking though the last hotfixes, this one might be the culprit, although this 
is rather a gut feeling.

Betreff: Re: Firewall on xenserver

Hi Ghait,

This doesn’t sound like normal behavior for XenServer 6.5 under CloudStack – 
I’m not aware of any issues requiring the XS firewall to be modified.

I would suggest rebuilding your hosts and re-add to CloudStack. With regards to 
OpenManage – I can see this does require some tweaking of firewalls 
(http://blog.hostduplex.com/2015/01/31/install-dell-openmanage-xenserver-6-5/ ) 
– but even this doesn’t require you to disable the firewall (this blog post 
suggests just adding a rule and restarting iptables).

All in all my advice would be to troubleshoot and fix the underlying issue 
rather than disabling iptables – which could be a potential security issue.

    The purpose for it as below :

    1-the system VMs agent showing not running , after I stopped the firewall 
in xenservers its working normally
    2-the instances accessible only when I stop the iptables from xenservers
    2- I installed open manage in the servers (Manage hardware for Dell 
servers) that need changes from iptables )

    I have advanced zone with ACS 4.8 and xenserver 6.5

    Hi Ghait,

    Can you explain your rationale  - i.e. what is the purpose of you changing 
XenServer firewall rules?

    Citrix seems to have a how-to article on 
https://support.citrix.com/article/CTX123930 .
