I have three Netgear Routers: WNDR3700, WNDR4000, and WNDR4500. On the SAME wired network, the 3700 works great. But both the 4000 and 4500 exhibit the same symptom. They periodically drop WAN connections for a minute (almost exactly), then allow them for 5-20 seconds, drop them for another minute, etc. In the plots below, red in the time graphs means that traceroutes and pings are not getting

Okay, so I have 10 VPC's each with a direct connect link and back up VPN's. Last night my direct connect went down (suspected related with DDoS), and my VPN tunnels took over. One environment, nothing working. Checked tunnel statuses on my end and AWS (looked good and even showed BGP route propagation.) Packets leave my firewall on the
Proxy servers cũng khó khăn hơn trong việc cài đặt và duy trì so với tường lửa. Mặc dù vậy, nếu proxy server được cấu hình đúng cách sẽ cải thiện được vấn đề bảo mật và hiệu suất cho mạng. Các proxy đều có khả năng mà các tường lửa thông thường không thể cung cấp.

However, I believe the result will be the same on this case. IGMP snooping on L2 switch for Multicast network in the Access Layer. Note: The gateway router must support IGMP proxy/query function or IGMP snooping on L2 switch will not work as expected. Topology: Target/Requirement: Using a TP-Link L2 switch’s IGMP snooping feature to build up a L2 multicast network to avoid broadcast of multicast data. Jun 19, 2020 · IGMP or Internet Group Management Protocol is an advanced internet option used for multicast traffic on VLANs.

The general Membership Query is used to find out all multicast groups that the stations are subscribed to. To put it simple, if I set the LAN to IGMP proxy, the WAN to IGMP router, everything works; If I set the LAN to IGMP proxy and THE Internal interface, which is the VPN interface, to the IGMP router, it won't work. The RRAS configuration is default with DHCP allocation.
