Hi there, I´m trying to configure a pool selection based on Giaddr but the
problem is that Relay Agent IP (Giaddr) doesnt belongs to same subnet as
the client pool so I guess I need to define a class that matches this
criteria (maybe of sure that I difined in a wrong way). This is not working
because it´s saying that network segment is unknown. Here is my dhcpd.conf
and syslog output
log-facility local5;
allow booting;
allow bootp;
lease-file-name "/var/db/dhcpd_wimax.leases";
ddns-update-style none;
ignore client-updates;
default-lease-time 43200;
max-lease-time 86400;
authoritative;
log ( info, concat( "circuit-id: ", option agent.circuit-id));
log(debug, concat ("giaddr: ", binary-to-ascii(10,8, ".", packet(24,4)))) ;
option domain-name-servers x.x.x.x;
option subnet-mask 255.255.255.0;
class "WAC" {
match if (binary-to-ascii(10,8, ".", packet(24,4)) =
"192.168.0.1");
}
subnet 172.17.2.0 netmask 255.255.255.0
{
pool
{
allow members of "WAC";
range 172.17.2.2 172.17.2.100;
next-server 192.168.11.60;
filename "/pxelinux.0";
option routers 172.17.2.254;
option subnet-mask 255.255.255.0;
option ntp-servers 192.168.22.240;
}
}
Syslog Message:
dhcpd: DHCPDISCOVER from 00:16:35:3e:0d:e5 via 192.168.0.1: unknown network
segment
thanks,
Dario Aguilar
