[Fwbuilder-discussion] virtualbox, bridged guests and iptables on the host system

[Greg <j.g...@gm...>]

I have a host server running centos 4 and virtualbox 3.x. The guests
are various loads (windows xp, server 2003, redhat, solaris etc).
Instead of managing firewall on each of the guests I would like to
manage all the guests connections via iptables on the host itself.

Using the default Centos iptables rules i cannot connect to the guests
on the host. So I built a rule for the host and noticed when i did all
connections to the guest were now open. I am now trying to figure out
how to close them down again.

How would I go about locking down the ports for guests on a virtualbox
host system using Firewall builder. I have tried creating another
interface and adding it to the FWBuilder firewall object but that did
not work. It created a vboxnet0:FWB1 instance when i ran
/sbin/ifconfig -a though.

thanks,

Greg
