Going from the Hetzner Rescue System to Proxmox with only 1 IP, full DHCP, no KVM Console access and port forwarding all in one easy to follow guide

Hi,
some quick notes:
The lines
iptables -t nat -A PREROUTING -p tcp -d 123.123.123.123 --dport 443 -i vmbr1 -j DNAT --to-destination 10.0.0.10:443
iptables -t nat -A PREROUTING -p tcp -d 123.123.123.123 --dport 80 -i vmbr1 -j DNAT --to-destination 10.0.0.10:80
are incorrect if you follow the previous instructions. It should be vmbr0 on both lines.
Small typo in the following lines:
post-up iptables -t nat -A PREROUTING -p tcp -d 123.123.123.123 --dport 443 -i vmbr1 -j DNAT --to-destination 10.0.0.10:443
post-ip iptables -t nat -A PREROUTING -p tcp -d 123.123.123.123 --dport 80 -i vmbr1 -j DNAT --to-destination 10.0.0.10:80
Second one should be post-up as well obviously.
After adding the iptables prerouting part, I am not able to reach my container. I can get out allright. I wonder why i can’t reach it though. At first I thought it might be that ip forwarding must be activated, but changing that didn’t help.
I figured it out btw. The problem was (as always) the Hetzner firewall 
Thank you for the tutorial.
Hello and thanks for that awesome tutorial, now i have a question, can SDN be used to assign IPv6 address to VM’s, as hetzner /64 IPv6 can be useful for some projects, thanks in advance.
Thanks, will update the guide
Hi, is this for UEFI or legacy BIOS?
