Request: Revisor blocked sites control system found that page https://vip-club-vulkan.net/ is accessible, Revisor's report contains the code 409. The page is not loaded, but the access is present.

Trouble resolution: check the MTU on the router before the VAS Experts DPI, the problem relates to the packets fragmentation and is solved as follows: specifying only hardware mtu (jumba frame) is not sufficient, in addition it is necessary to set ip mtu to 1500. After that the site will be blocked, and consequently it will not fall into the blocked sites control system report.
