Ok, I didn't know that.

That sounds like the best solution, but

1. I've got a Nortel/Symbol Card. I read about reports people use this card
succesful in managed mode, but nothing about repeater mode. Do you think
this will work.

2. This leads me to the problem, why I actually posted to this list. My Card
is in a PCI adapter which is NOT with a PLX chip. 

Here again the belonging part of my first post:

(End of quote)

It would be very nice, if anybody could give me an assessment for this.

Masquerading ervery connection 2 times is just needless and I worry it will
fail with some  protocols like ftp or messengers. Ok, I know no concretely
reason, ist just a fear.
