IP source address spoofing protection

[CotyMick]

Hey All!

Does anyone know if changing the IP source address spoofing protection mode from Log to Block will cause a disruption of network services during the change?

Thanks,

I can't say for certain, as I applied this to all of my networks when it first became available and didn't notice anything, but I also wan'st looking for any sort of network blip.

I would imagine it would not cause a network service interruption. I would hope that if it did, it would warn you accordingly, and I just tested it in my lab and got no warning.

Don't see anything about it here either:

It wont cause any disruption.

If something was doing it at the moment return traffic could not get routed to it, and it would already be broken.
