Proxmox VE 7.2 server with VM router for IP Address distribution for Vms

[galvatec]

I have this Proxmox hosted on oneprovider.com with only one IP and I need to make this IP reach the OS router for it to distribute internet and Vms.

I created a VM with Nethserver and configured it as a gateway for the other VMs and now these others are getting IP and accessing the internet

Now my question is how can I access the Nwethserver through the public IP and thus be able to redirect the ports to the VMs?

Hi,

Using iptables in your PVE network configuration, e.g.:

post-up iptables -t nat -A PREROUTING -i vmbr0 -p tcp --dport <PORT> -j DNAT --to <VM or CT Ip address>:<PORT>
post-down iptables -t nat -D PREROUTING -i vmbr0 -p tcp --dport <PORT> -j DNAT --to <VM or CT Ip address>:<PORT>
