Problems getting Apache Webserver and Forward Proxy running

Hello all. First off I am a newbie, so the answer my be simple, but 3 days of head butting and I'm at my limit. I am trying to accomplish 2 things. Create a web server, and create a forward proxy. I downloaded Apache to do both of these things. I am working on Ubuntu 18.04 Server, on it's own machine, not a virtualbox. I have a domain name registered as well.

I'll start with trying to fix the webserver, and see if that alone fixes the problem. NGINX used to work on this machine, so I think Apache should too. I can access the webserver from my local IP, just not externally.

My first thought could be the problem is ports. My router info is:

Device : homeserver
Current Address : 172.16...
Device Status : Connected DHCP
Firewall: Enabled
Address Assignment : Private from pool: 172.16...
WAN IP Mapping : Router WAN IP address (default)
Cascaded Router: No

Firewall Active
The firewall actively blocks access of unwanted activity from the Internet.

Current Applications, Pinholes and DMZ Settings: Custom
Device Allowed Applications Application Type Protocol Port Number(s) Public IP
homeserver HTTPS Server - tcp 443 64.110...
HTTP Server - tcp 80 64.110...
Static IP:172.16.. - - udp 9308 64.110...
Static IP:172.16... - - tcp 8080 64.110....​

This is the device details:

Device Details:

• Connection Type: Ethernet
• IP Address:
  172.16.
• LAN IP Address Allocation: Static
• IP Address Type: Private (NAT)

So, I think I have a static IP according to my router. And it appears that my ports are listening. (canyouhearme ... disagrees). So my next thought is that IP Address Type: Private (NAT). I have heard that IPs will block those ports, so maybe it's out of my hands and I'm trying to do the impossible. But NGINX used to work on this machine, on this IP, so I believe Apache should work to. So here is some info from the server itself:

drew@homeserver:/etc/apache2/mods-enabled$ sudo ufw status
Status: active

To Action From

Apache ALLOW Anywhere
OpenSSH ALLOW Anywhere

Apache Full (v6) ALLOW Anywhere (v6)
80/tcp (v6) ALLOW Anywhere (v6)
443/tcp (v6) ALLOW Anywhere (v6)​

probably more rules than needed... the result of headbanging troubleshooting...

Apache seems to be listening tcp6 to port :80, and :8080. Wait... should it be listening on tcp, not tcp6? Could this be why I can access locally, but not externally? Not sure how to change this, must be apache2 config file. Or ports config file. I'll work on those, but if someone can help me at this point, I'd appreciate it. Even if it's to tell me I'm doing something that isn't possible... so I can move on.

I'll post the config files if I can't figure out the problems there, and also if I do figure it out.

 

Ok, so that should be fine. tcp6 if fails, should default to tcp, if I understand correctly. So moving on..

 

Seems you are hosting the Server in your own premises (Home) therefore, in such scenario you need to set port forwarding on your router.
