To add some filter rules in conf file

[Ashmath Khan]

Sorry.. i missed that, client didn't request those options. Its working now.
But I had these further:

1. Is it possible to group the options together so that I refer them by some
name ? like in the below example instead of giving router-discovery and
boot-size, I can just give a group name, which will select those options.

2.  is it possible to have wild chars in the search string ? like if I want
to search the string "Phone*client" or "Alcatel?client" etc. I think i can
use the existing eval expressions to search the strings, but then I need to
parse these wild char strings, understand them, and apply eval expressions.
Is there any direct method which would recognize wild chars ?

3. Say I have this rule below: And rule1 passes, rule2 fails, and I saw that
it doesn't go into third pool i.e, rule2 deny one, which seems to be
correct. It means once it finds a pool match, then it won't evaluate other
pools. Is this understanding correct ?
class "rule1" {
match if substring (option vendor-class-identifier, 0, 4) = "MSFT";
}

class "rule2" {
match if substring (option dhcp-option-overload, 0, 4) = "NSFT";
}


subnet 192.168.1.0 netmask 255.255.255.0 {

pool {
option router-discovery off;
option domain-name-servers 192.168.1.254;
range 192.168.1.66;
allow members of "rule1";
}

pool {
option router-discovery off;
option domain-name-servers 192.168.1.111;
range 192.168.1.100;
allow members of "rule2";
}

pool {
option router-discovery on;
option domain-name-servers 192.168.1.222;
option boot-size 512;
range 192.168.1.200;
deny members of "rule2";
}


default-lease-time 86500;
max-lease-time 86500;
option routers 192.168.1.254;

}

thanks
