Backstory, Until now, I have used Ubuntu 16.04 Workstation, and now, on a new box, am playing with Ubuntu Server 16.04.3 LTS. Fast forward to setting up a LAMP stack, I cannot for the life of me figure out why I cannot access my box when I could 2 days ago.
I have assigned a static IP to my Ubuntu box and setup port forwarding (neither was nessesory beforehand). I am using No-IP's dynamic DNS service - configured through my router. UFW is configured to allow in Apache Full (80,443) from anywhere.
It should be working just fine dammit.. but it isn't.
The UFW log (/var/log/ufw.log) shows 1 block when I try access my public IP but seems to be IGMP related (I don't know anything about IGMP) so what do you think is going on here? Am I missing something in the setup that is usually taken care of in Ubuntu Workstation?
Dec 26 19:31:31 ubuntu kernel: [28828.327908] [UFW BLOCK] IN=enp0s25 OUT= MAC=01:00:5e:00:00:01*10:13:31:a5:a0:e0*08:00 SRC=0.0.0.0 DST=224.0.0.1 LEN=32 TOS=0x00 PREC=0xC0 TTL=1 ID=0 DF PROTO=2
EDIT: Before going to Ubuntu Server, I was relying on NAT-PMP/UPnP and never touched the modem aside to get my local IP. Also noticed that Ubuntu Workstation was using the old eth0 instead of enp0s25 in Server.
