Fedora xen - Dec 2006 - FC6 xen networking: child domain can''t see outside and vice versa

Hi List,

I have deployed xen in FC6 and setup one child domain. Child is
working fine but it is facing problem to access to outer world. It can
ping to dom0 but can''t ping other host. Same dom0 can ping this child
domain but no other host can. xen is configured to use route mode. And
dom0 using 12.158.188.XXX and child domain using 12.158.190.XXX. child
IP has been routed to dom0. Child domain has set to use eth0 as
gateway. There is no firewall at dom0. Forwarding is also enabled at
dom0. Please advise to solve this problem.

Thanks,
