LAN PORT ISOLATION
Does anyone know whether there is an effective packet isolation between Ethernet LAN ports on this router when a device with NIC connected to any of four LAN ports broadcasts with a destination MAC address: "FF: FF :...: FF" other LAN ports do not see that message ?
In other words, between any LAN ports exists an effective router isolation. There are routers where such isolation does not exist.
.
Everything was correct in my message.
I found that any SOHO type routers including Netgear's do not provide isolation between their LAN ports by a simple test pinging from PC connected to a LAN port through the router gateway to another LAN port where is connected my device.
Probably, I would get the needed isolation by cascading two routers together and doing the same test.
Why is needed to have an isolation ? I created a home network using 3 Netgear's PLCs and 2 TP-Link's devices. Everything regarding the two-way communications worked out when I connected one TP-Link's PLC to my router's LAN1 port and one Netgear's PLC to LAN2 port
accordingly.
However, I noticed an issue with TP-Links's Utility when it broadcasts a message "Who is there ?" Netgear's PLCs respond but
TP-Link's do not have a chance - "no device connected". Using (activating ) Netgear's Genie, it discovers all five powerline devices.
So, the culprit is the backdoor path from LAN port through router to other LAN port. In my opinion, it is equired an upgrade/
improvement with TP-Link PLC Utility instead of finding more complex a hardware layout solution. We exchanged a number of emails
with an engineer in Shenzen, China where TP-Link, LTD. is located.

Not I.

you tried/considered using a broadcast IP address?Is there some actual problem which you are trying to solve?
