| You're welcome Thomas. I've done a lot of work with ICS and, to the
| best of my knowledge, it isn't possible to have ICS clients
| automatically use the host's non-shared ISDN connection when that
| connection is open. ICS can only share one connection at a time.
|
| The only software solution I know of would be for you to manually
| enable ICS on the ISDN connection when it's open, then manually enable
| ICS on the original connection when you close the ISDN connection.
|
| You might be able to find a third-party Internet sharing program that
| can do what you want.
|
| I'd buy an inexpensive home broadband router and eliminate the
| problem. Another benefit of using the router would be that you could
| turn off the former host computer without affecting the other
| computers.

Thanks again, Steve, but I still have the feeling, there is a
misunderstanding. let me try to comment.

I just don't want to use the non-shared ISDN connection from the client.
ICS should continue via the DSL connection which is not interrupted. The
ISDN connection should be used for some host's private activities.

| enable ICS on the ISDN connection when it's open, then manually enable
| ICS on the original connection when you close the ISDN connection.
I agree, if I wanted to switch ICS to another connection.

A bit contraproductive ;-)

Would not help me either, because there are other situations when I want
to connect to another DSL provider from a client directly. This
currently works fine because the DSL modem is on the ethernet LAN and
therefore directly accessible from the clients, too. 2 ore more
connections from different computers are handled by the modem easily,
but there is no router that is able to do this (as far as I know).
Thanks
Thomas
