*Hi,*
Now on each realserver i have 2 Nic's. (ex: 192.168.1.58/192.168.2.58)

My directory forwards all the requests on 192.168.1.58 n/w.
I need to set the routing table on realservers that to use only director as
gateway if destination is 192.168.1.0 n/w.
For others use 192.168.2.0 n/w.

The reason is my mysql connections take double the time if i use the
director as gateway.

Please guide me how to go about.

Thanks,
Madan KN
