UFW logging and blocks

Postby bin » 18 Nov 2016 16:30

My logs are getting a lot of :-

[UFW BLOCK] IN=wlan0 OUT= MAC=01:00:5e:00:00:01:router mac address:08:00 SRC=192.168.1.254 DST=224.0.0.1 LEN=36 TOS=0x00 PREC=0xC0 TTL=1 ID=30122 DF PROTO=2

in my message logs.

From what I can fathom by searching this is something to do with Multicast and UFW.

Now, my machine is on a home network with a stock NAT ISP supplied router with all inbound ports blocked. Once in a blue moon it goes on my Mifi device if in use away from home - that also uses a private network address.

So - the question is do I really need UFW on all the time. I have no need for Multicast that I'm aware of.

Thanks

I'd say having additional security layer technically is better. there's no harm having ufw enabled so we can leave it enabled.
