uh, because that's how routing in the server PC works. you have to have=20
a different address for each interface.
your best bet is to either use the same interface (and change one of the=20
client's IP to something else (like 192.168.100.3) like so :

server             |         __________         client 1
eth0:192.168.100.1 |--------| ethernet |------| 192.168.0.2
                    |        |  switch  |
                             |__________|------| 192.168.0.3
                                                 client 2

or... change one of the subnets to use a different prefix, like so :

Server             |         | Client 1
eth0:192.168.100.1 |---------| 192.168.100.2
                    |                              | Client 2
eth1:192.168.101.1 |------------------------------| 192.168.101.2
