Complementing :

I use shorewall in all my PVE hosts, it works just fine, but you can use
"pure" iptables ...

And for internal comunication within VMs, I use a dummy network card, put
something like this in your /etc/network/interfaces

auto vmbr3
iface vmbr3 inet static
        bridge_ports dummy0
        bridge_maxwait 0
        address 10.1.1.1
        netmask 255.255.255.0
