Re: Question about migrating to IPv6 with multiple upstreams.

I have an interesting situation at a business that I am working on. We
currently have the office set up with redundant connections for their
mission critical servers and such, and also have a (cheap) cable modem for
general browsing on client machines.

The interesting part is that the client machines need to access some
customer networks via the main redundant network, so we have a firewall
set up to route those connections via the redundant connections, and
everything else via the cheaper, faster cable modem. NAT is used on both
outbound connections.

With IPv6, we are having some trouble coming up with a way to do this.
Since there is no NAT, does anyone have any ideas as to how this could be
accomplished?

In a nutshell: how do you have 2 upstream connections, and choose between
them based on outbound destination?

thanks,
-Randy



Standard IP routing, the default gateway of the network can decide based
on a route entry whether to send it to the cable modem or send it to the
firewall.
