RV082 "router busy" information after enabling TrendMicro Web protection

We have recently bought TrendMicro ProtectLink licences for our RV082 router. After enabling Web Protection (URL Filtering nad Web Reputation) on it, users inside local network began to recieve strange information (web page) during web browsing.

The information says:

"The router is very busy at the moment. Please try after a few minutes." You can press then OK or Retry - pressing OK do not help, the web page shows again "The router is very busy...".

Our network consist of one server (MS Windows 2003 SBS) and less than 15 workstations (including PCs and laptops). When we disable Web Protection on RV082, everything is OK and web browsing do not generate such information.

Anybody encountered such problem? Thank you in advance for your help.

Good Morning,

Typically the Trend Micro Protect Link filtering will take all the request (floods) that come into it and block them.

URL Overflow Control
Temporarily block URL requests (This is the recommended setting)
Temporarily bypass Trend Micro URL Filtering for requested URLs

You can change the setting to bypass the request or look into the traffic that you are filtering.

When you look at the log or counters what are you seeing the most blocks at.

URL Overflow Control

Temporarily block URL requests (Trend Micro recommended setting): Users will not be able to access the Internet until the current queue can accommodate more requests. Temporarily bypass Trend Micro URL verification for requested URLs: URL requests will temporarily bypass URL Filtering and Web Reputation Services. This could make your network vulnerable to threats.

You might want to look to break that category down to allow some of the traffic or educate the staff on what is allowed on the Internet.

I hope this helps out
