linux router with two gateways to internet

[fnijenlist <fnijenlist@bos.nl>]

I've to setup a small business netwerk with a debian router, the network is 
a 192.168.0.0/24 and the router has two gateways, a adsl connection and 
another broadband connection. Default gateway points to the adsl, all 
clients are masquereded.
Well, problem is that about 10 clients should be routed to the other 
broadband connection but just adding a host route won't give a internect 
connection.

route -n will show:

195.190.xxx.xxx 0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
213.93.xx.xx     0.0.0.0         255.255.255.192 U     0      0        0 eth0
10.0.0.0        0.0.0.0         255.255.255.0   U     0      0        0 eth2
192.168.0.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1
0.0.0.0         195.190.xxx.xxx 0.0.0.0         UG    0      0        0 ppp0

If i want to have a host routed to the eth0 i would add a route like

route add -host 192.168.0.10 dev eth0

general masquereding rule is added for the full 192.168.0.0/24 netwerk, it 
should figure out itself what external ip to use for the masquereding since 
routing will be done before ? masquereding.
But after adding a route I won't even get a reply from the router when I 
send echo-replys from the client to the router.
I'm probably missing a point here, anyone got an idea?

ps: due to some reasons we can't work with subnets, it has to be done with 
static host routes..
