I have a series of these items
Aug 06 12:57:22 Denied CONN=lan MAC= :08:00 SRC=10.159.11.20 DST=172.21.3.222 LEN=80 TOS=0x00 PREC=0x00 TTL=63 ID=19786 PROTO=UDP SPT=62104 DPT=54068 LEN=60 MARK=0x2 They come about every 15 minutes.
I understand many of the definitions of CONN, MAC, DST, LEN, etc., from the user manual. I don’t understand why I have the entries.
It seems to have something to do with my using Router-Block-Modem outbound firewall rules to block all private spaces, i.e, 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. When I removed the firewall rules, I stopped getting “Denied CONN” entries.
Are these serious entries or are they simply something I’ll have to ignore if I can’t fix?
