Different routes

[Arthur Kerpician <arthur@xxxxxxxxxxx>]

Hi,
The server I'm using is doing SNAT for the local network and has 2 NICs 
for 2 different ISPs and 1 NIC for the LAN. One of the ISPs is the 
backup one and the default gateway on the server is switched to this one 
if the primary one is down.
Now, how can I route several LAN clients (not all) through the backup 
connection, instead of the default one?

Thanks for the help,
Arthur
