I questioned this in the ASL support forum and mike gave this answer:iptables: Unknown error 18446744073709551615
I do have a VPS, and upon inspection I found that I had two firewalls operating...one as the default VPS firewall, and another I had added from the Plesk interface added as a "module" when I first setup the VPS, I had entered some custom rules for some ip addresses to block...Its not ASL, thats a firewall error with iptables. Normally that happens with a 64bit box from what I recall. It usually means you are missing an iptables module - or on a VPS a module is not initialized for that container. Unfortunately, iptables sucks with its error messages and isnt clear about whats missing.
Following the tip given by Mike, I decided to remove the "module" firewall, leaving the default VPS firewall. The settings are in the "normal" mode, and I have added no rules or changes to this configuration...
Although things seem to be normal, and the IPtables seem to be intact, showing all the blacklist entries from the ASL interface, is there any recommendations I might consider changing on the default settings?
And, should I stop or restart any services that may be affected by the the module removal?
Also, it seems the errors were only there for a few days, then they stopped completely, even before I removed the module....
I know some one out there is saying to themselves that I should be posting in the plesk forums, but it usually takes a day or two after posting before it hits the public view, then response is slow...this forum is far more informative, responsive and usually right on in the answers...
Thanks
