Assuming your subnet mask is 255.255.255.0, you have both interfaces on the
same subnet, which won't work. You have two options:
1. Change the third number on the DSL router and on eth1, e.g. 192.168.2.100
and 192.168.2.111
2. Change the third number on eth0 and all the other computers and devices.
Either of the above options will work. Choose whichever gives you least hassle.
You need to make sure that all of the other devices have the address of your
server's eth0 set as their default gateway. The server needs to have the
address of the router as its default gateway.
If the other devices want to get their addresses via DHCP (a good idea), you
will need to run a DHCP server on your server machine, as they will be isolated
from the router.
You will also need to make sure IP forwarding is enabled on the server.
