The domU can ping dom0, but not outside Xen, and vice versa.
 
I test in domU:
 
#ping 10.0.0.150    /*10.0.0.150 is an external IP in LAN*/

From 10.0.0.36 icmp_seq=307 Destination Host Unreachable
From 10.0.0.36 icmp_seq=308 Destination Host Unreachable
 
I test in dom0:
 
#tcpdump -i peth0 | grep "10.0.0.36"    /*10.0.0.36 is domu's IP*/

It seems everything is all right.
I don't know what is wrong. Can anyone help?
 
Thanks in advance,
