Fwbuilder is working great.
I'm wondering if it is possible to make a Global policy on eth0 (Workstation) that will apply to
th Virtual Machines sharing eth0 bridged connection ?
Virtualbox (guest=linux) on my Linux host (eth0),
using bridged networking for the virtual machine on eth0.
The Virtual Machine ignores the fwbuilder iptables and connects via eth0…
Is there a way to apply a global policy that any connection made on eth0 will follow, regardless if it's from the workstation or the Virtual Machine?
If you are using Xen you might want to check out this blog post by Marco:
There was a recent discussion about this on the mailing list, so if you aren't already subscribed that also a good place to get information.
Please let us know how things turn out.
That link is for Virtual Private Server Virtualization but I believe there are simularites in concept for bridged interfaces.
I'm swamped at the moment with Fwbuilder making adjustments to the GUI.
Will report back when possible.
I believe this might lead to a solution;
"integrate ebtables and iptables, using the iptables module physdev"
"If you need to filter or translate ARP traffic (at link layer), your firewall has bridged interfaces (for example a transparent bridge between a OpenVPN tunneled VLAN and a local VLAN, or bridged interfaces for virtualization), ebtables(8) is your friend."
