Nestacilo by nemazat tu sit na eth1 a siti na shaper0 dat mensi
metriku, nebo jenom presmerovat default gw bez odstraneni site na eth1.

Nebo jeste dalsi moznost :-) 

Rozdelit si sit na dve mensi (prodlouzime netmask) a posleme je pres
shaper0. Routovani se ridi podle nejdelsi netmasky, takze:

route add -net 194.169.2.0 netmask 255.255.255.128 dev shaper0
route add -net 194.169.2.128 netmask 255.255.255.128 dev shaper0
