DHCP Static Route / DNS Suffix options?

Hi,
I've got my routing working between two offices now, but on the client PC's
I need to add my static route with a metric above 1. This is because users
often create a vpn client connection to customers to access their servers
via VNC etc, and these often have the same IP ranges we use. I can't see
this option in DHCP options, only the address/gateway routing pair?
In addition, I'd like to be able to add two DNS Suffix search options, so
that users here can connect to machines in either office without giving a
fqdn. I've replicated DNS to each office, but it still needs the domain name
bolted on the end to work. I have set this manually on my pc for testing,
but there must be an easier way?
Cheers,
James
 
If you connect a LAN machine to another network which uses the same IP
subnet, fiddling with the routing won't have any effect. If your machine has
a packet for a 192.168.0.x/24 address and its LAN IP 192.168.0.y/24, it
will never be routed anywhere. TCP/IP will see it as a local address, and
try to deliver it on the local LAN by direct delivery (ie over Ethernet
using hardware addressing). It will never get to a router. The software only
starts looking at routes if the address is not local.

Even if you could get a packet to the remote machine, it would never
reply for the same reason. It would see the address as local.
