iptables -t nat -A PREROUTING -p tcp -d 192.168.30.5 --dport 80 -i vmbr0 -j DNAT --to-destination 192.168.30.103:80
iptables -t nat -A PREROUTING -p tcp -d 192.168.30.5 --dport 443 -i vmbr0 -j DNAT --to-destination 192.168.30.103:443
iptables -t nat -A PREROUTING -p tcp -d 192.168.30.5 --dport 3389 -i vmbr0 -j DNAT --to-destination 192.168.30.103:3389

Hey,

your VMs are on the same network, you don't need NAT. Could you reboot the host, so iptables is reset. Then could you check if the VM can ping the router and the PVE host. Additionally can you reach 1.1.1.1 from the host and from the VM?

Ey,

Sus máquinas virtuales están en la misma red, no necesita NAT. ¿Podría reiniciar el host para restablecer iptables? Luego, ¿podría verificar si la máquina virtual puede hacer ping al enrutador y al host PVE? Además, ¿puede comunicarse 1.1.1.1desde el host y desde la máquina virtual?

hi , I can ping from my virtual machine for gateway and for my entire LAN network, in the same way with a PC I can ping my virtual machine and everything is excellent, in fact from Proxmox I can ping Google and he does have internet, but the virtual machine does not have internet nor does it ping Google

Do you have the firewall enabled on you PVE host?

Do you have the firewall enabled on you PVE host?

I don't have a firewall it's a new server that I just formatted, I presume it's some routing but I don't know, has something like this happened to someone ?
