Dns problem I think– Help

[cat1947]

Ok here is the set up
Running version 1.2 embedded
alex wrap board
vr1 = wan port dhcp
vr0= lan1

vr2 is serveral vlans
Each vlan has its own dhcp server

everything on lan1 works great.  Every site I try to open, does open.

On the vlans  most sites open.   But I have a problem with some sites not opening which do open on lan1
For example yahoo.com will open on lan1 but not on any of the vlans.  I even tried the ip and it would not open on the vlans.  A very strange problem.

Any ideas would be appreciated.
