Multiple gateways



Dear NG,

We have two internet connections, cable and DSL as a backup, we would like
to start hosting our own exchange server, the exchange server is a DC with
two nics and gateway'ing to the cable, we don't feel like hosting exchange
over cable because we cant get a static ip so we decided to use the second
nic with the DSL where we have a block of 5 usable IP's, my question is will
I have an issue if I register two ip's to the DNS considering that its a DC?
what will become the default route considering that I want to keep cable as
the default route? will exchange always route the DSL? here is an example on
how I plan do this...

NIC 1 - Currently registered with DNS
IP = 192.168.10.200 - Nat'ed behind the cable router
SM = 255.255.255.0
GW= 192.168.10.1
DNS= 192.168.10.200

NIC 2 - Currently not used
IP = 192.168.20.200 - Nat'ed behind the DSL router
SM = 255.255.255.0
GW = 192.168.20.1
DNS = 192.168.20.200

SMTP will be configured to listen to All Assigned ip's

is this ok?

Thanks for your help
