I was actually being serious, it's not, it doesn't have to, and in the case that started this discussion it probably would have been sufficient to just drop tcp/80 to his link since I would be it's 'business dsl' so he gets an 'SLA' not so he can run a business critical web service there. There are services you can buy that are a lot more expensive, but why would you? if there are options that are more relevant and cheaper... and in line with what you want. You can certainly pay more if you want to, I'm not sure that's the smart choice though. -Chris > On Fri, Jul 10, 2009 at 6:16 PM, Christopher > Morrow<morrowc.li...@gmail.com> wrote: >> On Fri, Jul 10, 2009 at 5:49 PM, Luan Nguyen<l...@netcraftsmen.net> wrote: >>> Filter like in using the Cisco Guard of sort, to send the good traffic back >>> to the customers?
