I added a warning about the cron period. Our iptables bytecounters overflowed within an hour when we had constant download at 60Mbps. We calculated (based on the maxiumum value we had seen accounted and the 100Mbps network connection) that we should run the cron every 15 mins. Should consider even more frequently if using a Gbit connection.[[User:Robferrer|Robferrer]] 07:08, 14 May 2008 (EDT)

This guide is very flawed for 99% of VPS hosts who offer more than 1 IP address with a vps account. --[[User:Vpsspeed|Vpsspeed]] 14:34, 13 June 2009 (UTC)
