Hi Simon.
Yes for the X.X.X it's same every where. I have just made a search/replace.
For the subnet declaration do you mean I should do this :
.subnet X.X.X160 netmask 255.255.255.224 {
option routers X.X.X.161;
option subnet-mask 255.255.255.224;
option nis-domain "mynisdomain.com";
option domain-name "mydomain.org";
option domain-name-servers Y.Y.Y.3, Y.Y.Y.3;
range X.X.X.162 X.X.X.190;
default-lease-time 21600;
max-lease-time 43200;
}
Thank you.
Eugène NG
