Hi List,

after lot's of trial and error I setup three internal networks for LAN, LAN2
and DMZ. All domU's can connect to each other. My two ethernet devices are
passed to a domU.

Well, so far - so good...

But: After all this "netwrking" I did the following:

created another dummy in dom0

        ifconfig dummy4 up
        brctl addif brLAN dummy4

Interface came up but ping from domU to dom0 remaind quiet (no tcpdump

Then I tried to activate arp

        ip link set dummy4 arp on

and tcpdump -i brLAN told me "arp who-has tell"

Any idea what small detail I missed?

I'm feeling quite close to a solution - but the last step....

btw, there's actually no firewall software running yet (as I'm installing
offline). So any connection should be possible for now.

On my dom0 the "ip r" is: dev dummy4 proto kernel scope link src

iptables -L is completely empty

and /proc/sys/net/ip4/ip_forward is "0"

Any idea what small detail I'm missing???
