RE: [Xen-users] bridge-utils problem

[Tommy Huang <tommy24@xxxxxxxx>]

Hi,

I found that once I "ifdown xenbr0". Then the machine can connect to the 
Internet immediately.
By the way, I allow all traffic in iptables. So the firewall should not be 
problem now.
Any thought? Thanks in advance.

Regards,
- Tommy
