Unable to add a firewall rule to Plesk Panel V 11.0.9 running in centOS 5.8

[gatkin]

I am using Plesk Panel 11.0.9 update #59 with centOS 5.8 (final)

I installed the Firewall extension. V 1.0.1 I then added three IP addresses I want to block and these are in a new Firewall Rule.

I then see the following message at the top of the webpage

Warning: The changes you made to the firewall
configuration have not yet been applied to the server.
To do it, click `Apply configuration`.
'
When I click on "apply configuration" and follow the prompts Plesk Panel crashes and I have to reboot the server to start the Plask Panel service. I am unable to add the new Firewall rule.

Can anyone please help

Are you trying to add firewall rule on your VPS server ?

Yes. I have a virtual centOS server at goDaddy.com. When I add a firewall rule to block an IP address , when I activate the rule then Plesk service crashes.

There is an issues with your VM firewall modules/setting, First you will have to check your firewall setting rules on your server and after that try to add new rules on your PSA firewall.
