Hi,
I'm moving a connection from an ISP to another. Both connection need to
run concurrently for a time.
The ISA server is on the current connection and will eventually be moved
to the new connection. While both connections are running a small hardware
firewall/portfilter will run the new connection.
At some point we will want to switch all traffic through the new
connection but leave an easy path to switch back.
My plan is to remove the default gateway entry from the outside NIC of ISA
and specify the new connections internet IP as the default gateway on the
Internal NIC of ISA.

Does anyone have any views of how well this will work?
Will ISA do any caching with this setup?

many thanks,
Iain.
