Hi,
I have set up my Xen 3.0.2 on a 64 bit gentoo using bridging, because I
want to have a seperate IP adress for each domU. I can send out tcp
packets from my dom1, but I don''t get their reply. I can ping the dom0
from my dom1 and vice versa - no problem there. If I ping from my dom1
to an external internet adress, I can see (using tcpdump) the outgoing
packets in the dom1:eth0, the xenbr0 and the response coming back to the
xenbr0 (and my dom0:eth0), but no such packets in the dom1:eth0. If I
ping the dom1 from the outside I can see the packets received by xenbr0,
but not by the dom1:eth0. Any ideas ?
thank you very much,
Oliver
