Cisco R180w

I have two remote small offices with Cisco R180w using VPN tunnel to a netgear FVS318G.  I cannot get DNS to work  from these remote offices to our corporate.  The VPN connection has been working fine and i am able to do everything by ip address.  Can someone explain how to pass DNS traffic over the VPN tunnel to our DNS server?  I do not have an opportunity to put dns servers in the remote offices since they only have 2 to 3 computers and VPN has worked fine.

I have access rules for dns from LAN to WAN setup on the Cisco and Lan to Wan from netgear box.

cisco lan is
Action:Lan to Wan                               
Source IP: ANY       
Destination IP: (dns server IP)       
gateway:public ip for tunnel

Netgear lan

destination IP:
gateway:public ip for tunnel

Then try putting an appropriate entry in your local HOSTS file (each of the small number of computers). You know the VPN works and traffic flows by using IP address.  

Make an entry in HOSTS that looks like  Servername   # for remote server.

You need to make the entry fit your circumstances and you need to be administrator to change the HOSTS file.

I don't think so. I think you need to set for each computer.
