I was going through my daily morning firewall report and saw these rules strange rules
Chain OUTPUT (policy ACCEPT 40383 packets, 7815K bytes) num pkts bytes target prot opt in out source destination 1 4365 444K DROP icmp -- any any !127.68.53.96 !127.81.42.69 icmp port-unreachable connmark match ! 0x7b2ff1ce 2 2880 115K DROP tcp -- any any !127.36.111.188 !127.182.29.205 tcp spts:61001:65535 flags:RST/RST connmark match ! 0x72dcd57d
They're in the 127.0.0.0/8 range so they're in the loopback address range. They're oddly specific though. My server auto patches itself every morning at 7:30am. The only services that aren't patched are softether vpn. It also runs my own voip server but that runs in its own account. These rules weren't there in yesterday's daily morning firewall report. I have fail2ban running but this doesn't seem like a likely source. My other firewall rules haven't been touched.
What does this mean for me?
