Re: 3 Server solution

Thanks for your quick response David. I do have a real IP address on the
server configured on eth0 as xx.xxx.xx.44
and now that I have removed the loopback entry the server is responding fine
on .44.

Anything else I should look into before I try the loopback setup again? in
my view since this is a loopback entry it should only response if the real
IP is not responding isnt that the case ?

Imran.
