Thanks Paul,

thats exactly what i tried before, but it even did not work on fedora 
core. This will mean, i have to make some kind of hack the get the 
routing fixed in the routing table. I'm gonna write a very little 
shell-script and let it execute on boot-up. I think, on windoze i can 
indicate them also as fixed route per client. :-( It would have been 
luxury...
