RE: [Xen-users] private interconnect problem

[Javed Asif <jia786@xxxxxxxxxxx>]

OK I have established 2 VLANs.
One public 192.168.1.1 using router as shown in attached diagram.
Other private VLAN using a switch.
Now Dom0 and aasbanas can ping on private VLAN. But dom0 and aasbanas can't ping ebdb1-priv and ebdb2-priv and vice versa.
 
How can domu's private interconnect can see out side and vice versa?
