Is it icmp mode work? #429

Closed Cwek closed 2 years ago

Cwek commented 2 years ago

As title. And some question for config.

Is it need to set /proc/sys/net/ipv4/icmp_echo_ignore_all to 1?
Does the size of the sock-buf need to be smaller than the MTU value of the link, for example, less than 1500?

I am using icmp. It works normally.

And some question for config.

Not needed.

No.
