[cobalt-developers] Is it possible to have separate gateways for each NIC on QUBE3?

[support@xxxxxxxx (Technical Support)]

Does anyone know whether it is possible to have separate gateways for
each eth0 and eth1?  I have 2 routers and 2 DSL lines, my QUBE3 is
our mail server and I would like to allow switching from 1 gateway
to the other upon any downtime on DSL line 1.  i.e. a backup
configuration.  each of the IP addresses assigned to QUBE3 have been
NAT at router.  I can get each to work, but don't know how to make
the DSL2 gateway come alive upon death of DSL 1 or any intermitten
downtime without manual intervention.  And my experience in this
area is fairly new...

My goal is to not have to have to configure another linux box
for backup mail server2. SO MX records will point to Qube3.eth0
then Qube3.eth1 for user@xxxxxxxxxxxxxxx without me having to
change from GUI the gateway settings.

Any knowledge on this would be greatly appreciated.

Thank you,
