[ILUG] Routing question

[Niall O Broin]

I manage an office which has an Internet connection via a leased line.
However, bandwidth on this line is somewhat expensive. I'm planning to
install a DSL line (so obviously, the office isn't in Ireland :-( ) and use
that for most of the outgoing traffic. But how best to do it ? Can I add two
default routes to the clients, the route through the DSL machine having a
lower metric than that through the leased line ? Or should I make all the
clients have a default router to the DSL box, and then have that box's
default route be through the DSL connection except when the DSL is not
available for whatever reason, in which case it would route via the box on
the leased line. As I am doing NAT on the current firewall (connected to
the leased line) and I'll be doing NAT on the DSL box is that likely to
cause me some confusion ?
