Jul 13, 2017 SERIAL PORT PASSTHROUGH. Windows Server Hyper-V. In production environments there are times when we need to use serial ports. I have a brand new server with serial ports and now I have to have my host on my network so that I can use the serial ports, which I do not want. I'm very new to Proxmox and other bare metal hypervisors. I cannot for the life of me get a physical (local) serial port (COM1) passed through to a Windows 10.
Could someone show me how to forward ports from host to KVM guest (in NAT) mode? I am running Proxmox and I only have 1 IP address.
Thanks

1. add a bridge with some private subnet to your /etc/network/interfaces like:
instead of postrouting to eth0 you might need to use vmbr0 instead if it exists, this depends on if and how you setup default bridges at all..

2a. add at least a rule to forward one port for use with ssh one those private IP:
as you can see you can match different external and internal ports as you need.
make sure to not use the external ports you need on the host itself - so better not forward port 22 itself if you are using it on the hostnode for ssh and not forward 8006 with proxmox etc. ;-)
2b. you can also forward multiple ports with one rule:
2c. you can also forward port ranges like this:
3. in proxmox panel create a guest VM and assign the bridge and IP you choose in the rules above via network settings like 10.0.0.2/24 and use the internal IP of the bridge like 10.0.0.1 as gateway..
that's it. you could also add and remove forwarding rules like the above directly via cli, it's just an iptables command. having them in /etc/network/interfaces via post-up/post-down makes them permanent. instead one could probably use other things like persistent iptables and so on - feel free to adapt to your needs ;-)

Following @Falzo 's rules will do the job. Just some additions:
First of all, uncomment this line to /etc/sysctl.conf:
net.ipv4.ip_forward=1He suggested to use vmbr0 instead of eth0, I would say you should DEFINITELY follow this rule, adding a virtual interface to your host node, using proxmox. So, create a vmbr0 interface for using as the interface to your main ip and a vmbr1 for your nat ips:
Follow @Falzo 's guide for port forwarding to same ports (25 to 25 etc.) or for massing forwarding a range of ports. (Don't forget to restart network)
And if you want to reverse proxy a domain to your nat vps, so you don't have to use specific port in the address, install nginx to your host node and follow this configuration in your nginx domain config file (create in /etc/nginx/conf.d/ a file as mydomain.net.conf):
(assuming that your NAT vps you want to forward has the address 10.0.0.3)
P.S.:
Ka 52 vs mi 28. If you create or use vmbr0, then, don't forget to modify Falzo's rules like this:
