High Latency with IOS url filtering enabled

[clopezj07]

Im notice after configure the trend micro url filtering on a Cisco 2821 high latency on Http navigation, the latency on the ping for the requests shows a 245ms latency, but if i disable this feature on the router, returns to normal navigation and decrease the latency up to 70ms.

any idea what cause this issue, or if there's a parameter that could be helpfull to avoid this?

Regards.

I would suggest that you restrict traffic that is to be inspected by Trend Micro to only TCP/80 and TCP/443 instead of all TCP ports if you haven't already had this configured. This will ensure that only web traffic gets inspected by Trend Micro but not any other non web traffic ports.

Hi halim ,

How we can block urls like facebook and othersites in cisco 2821

Hello,

You can use Regex and create a local URL-filtering police working side by side with CBAC or ZBFW

You could use an external server to perform the URL filtering actions (websense, Trend micro, ScanSafe)

Hope I could help
