Hi All,

I would appreciate any assistance to help me understand how to get a website to be hosted from a proxmox VM behind a single IP, NAT is working from inside out, jjst trying to get the website to display with an A record pointing to my proxmox server?

I have everything working from the inside out, i.e. RDP, ssh, Zerotier, and so on. I have set up a docker Nginx reverse proxy and WordPress (in the process of typimng up a tutorial as I feel this is lacking for new users, such as myself) container to host multiple websites. all working locally. I have set up a DC level security group to open up ports 80, 443, and applied that at DC, NODE, and VM levels, etc I have also set iptables to forward incoming

e.g.
Code: 
iptables -t nat -A PREROUTING -d MYPUBLIC IP -p tcp --dport 443 -j DNAT --to 10.10.10.102:443
iptables -t nat -A PREROUTING -d MYPUBLICIP -p tcp --dport 80 -j DNAT --to 10.10.10.102:80

DC and Node PVEFW
Code: 
iptables -t nat -L

I run a
Code: 
dig +short myip.opendns.com @resolver1.opendns.com
. and it shows the correct public IP etc for the above. I am clearly missing something and just cannot figure it out how to open port 80 (443 I will attack later) I have the A records pointing to the proxmox server, I just can't seem to get the incoming request on port 80/443 to accept and forward to the internal VM that is hosting the website.

I answered my own question lol. I reset all my iptables and got rid of a mess I created. After reapplying I noticed that I had made a typo on the public IP. I will write up a tutorial in due course to help others as this is easy when understanding the architecture
 
Really looking forward to reading a tutorial. I'm not a stranger to servers, routers, firewalls and so on. But this is my first step in to VM and things are done differently.
As a new user I'm trying to get my head around the different ways things are done. It seems that this is one of the most asked topics for new users.

I agree it is indeed and I have just gone through a whole load of pain with proxmox, but fast getting up to speed. The bit that evades me, for now, is hosting multiple websites and I am stuck at WordPress error establishing a database. always the simple stuff that gets me, but I am collecting lots of info for a tutorial on publishing websites from a vm

Have you tried to install Wordpress through Turnkey in a container?

I have built WordPress with ubuntu VM's and turnkey and can get them to run locally with ip and across zerotier, I got over the database error, I am struggling to get port 80 to be connected to the VM via HAproxy out to public internet.

I have the DC to Node security group with 443 and 80 and I have in my interfaces the forwarding rules etc. I feel like I have done all the hard stuff. but this website area has me stumped....

One of the sites is through cloudflare .

I cant for the life of me figure out what's missing to expose the websites on the VMS out to 80 and 443, any ideas greatly welcomed.

I am thinking I need some sort of firewall in addition to proxmox??? not sure it's unclear. I do have a single nic with single IP and could open up another port but not sure I need to...
