Dual DSL lines one as backup. (Automatic Failover?)

[Paul Guibord]

I have a WIN2K server running ISA server that has dual DSL
connections to the internet using different ISP's for
each. If one of the DSL lines should go down I would love
to route outbound traffic over the bacup DSL line
dymanically. I realize I could run RIP on one of the
interfaces and configure RIP on the DSL router as well, to
determine weather or not the connection is active but I am
stuck with the static nature of the default gateway.

Any help or articles (links) on how to accomplish this
would be appreciated!!!

Thanks Paul

Hi Bill,

If you're using ISA Server firewalls, you can use a cool utility called
RainConnect www.rainfinity.com. It does fail over, load balancing, link
aggregation, and fail back. Very cool for ISA Server firewalls loaded on
Win2k/Win2003

HTH,

: You should be able to do that. If you configure two default routes
with
: different metrics, the system should use the one with the lower metric. If
: this gateway fails, dead gateway detection should switch you to the other
: default route.
:
: But this is a one way process. It will not automatically switch back
when
: the other gateway comes back up, as far as I know.
