Your picture shows br2 is connected to server's eth1. "brctl show"
from yuor attachment shows br2 is connected to dummy1, not eth1.

Hi Fajar,
The output from "brctl show" is done from dom-0.
There br0 provides access to the real world
All the others (br1, br2 and br3) are restricted to within the machine
So BR2 is connected to:
A) Dummy0 on dom-0
B) eth1 on kc3072 (vpn)
C) eth1 on kc3041 (fw-int)
The bridges themselves are only visible on the dom-0, not on the dom-U.
Involved (kc3041, kc3072) startup scripts:
