debian lenny xen bridge networking problem
- by Sasha
DomU isn't talking to the world, but it talks to Dom0.
Here are the tests that I made:
Dom0 (external networking is working):
ping 188.40.96.238 #Which is Domu's ip
PING 188.40.96.238 (188.40.96.238) 56(84) bytes of data.
64 bytes from 188.40.96.238: icmp_seq=1 ttl=64 time=0.092 ms
DomU:
ping 188.40.96.215 #Which is Dom0's ip
PING 188.40.96.215 (188.40.96.215) 56(84) bytes of data.
64 bytes from 188.40.96.215: icmp_seq=1 ttl=64 time=0.045 ms
ping 188.40.96.193 #Which is the gateway - fail
PING 188.40.96.193 (188.40.96.193) 56(84) bytes of data.
^C

The system is debian lenny with a normal setup.
Here is my configs:
