i just have 1 Public IP for proxmox server + 2 local IP for VM and i want to access the VM from outside (internet)

Create a firewall rules to pass ports to VM

like for TCP:
/sbin/iptables -t nat -A PREROUTING -p tcp -m tcp --syn -s 0.0.0.0/0.0.0.0 --sport 1024:65535 -d YOUR_INTERNET_IP/255.255.255.255 --dport PORT -m state --state NEW -j DNAT --to-destination LAN_VM_IPORT

i will try,
but is that for outgoing only or incoming too?

This rule needed only for incoming connection from outside. And communication continue until connection is closed.
