hello forum !
any configuration to manage multiple gateway in dhcpd scope
e.g

ddns-update-style interim;
dynamic-bootp-lease-length 86400;
max-lease-time 604800;
default-lease-time 604800;

subnet 10.10.1.0 netmask 255.255.255.0 {
option routers 10.10.1.1;
option subnet-mask 255.255.255.0;
option broadcast-address 10.10.1.255;
option nis-domain "xxx.com";
option domain-name "xxx.com";
option domain-name-servers 10.10.1.1;
option time-offset -18000;
authoritative;
option ntp-servers 10.10.1.1;
option netbios-name-servers 10.10.1.1;
option netbios-node-type 2;
range 10.10.1.40 10.10.1.254; }

this configuration apply client gateway 10.10.1.1 now i have client to fix using mac binding to select different


host servolinx {
next-server dhcp;
hardware ethernet 00:C0:26:783:03;
fixed-address 10.10.1.10;


gateway allocate to this mac 10.10.1.2 is this posible ? please right down script

the 10.10.1.2 address may still be valid in the dhcpd.leases file

It is probably in /var/lib/dhcp/dhcpd.leases
but check in man dhcpd.leases to be sure..

thx for reply 10.10.1.2 are another linux internet gateway machine e.g

LINUX 1
10.10.1.1 ip
xx.xx.xx.xx isp gateway


LINUX 2
10.10.1.2 ip
xx.xx.xx.xx isp gateway

Client 1
10.10.1.4 ip
10.10.1.1 gateway

Client 2
10.10.1.5 ip
10.10.1.2 gateway


now tell me how to manage both gateway using DHCPD service like:-
client 1 select gateway 1 and client 2 select gateway 2

thx in advance

If you create two scopes in the same subnet do they get used in a round-robin fashion? or there may be an option for this.

actully in 10.10.1.1 linux box machine are selected ports open like web , ftp , ssh .etc etc and 10.10.1.2 linux machine are all ports MASQUERADE so thats why i need to manage client gateway from dhcpd scope

so you want to use different gateways to reach different destination ip addresses?

yes dude any solution

point all your hosts at one default gateway via DHCP. Put routes onto the default gateway for the destinations available via the alternate gateway. Any traffic to the alternate destinations will get redirected by the DG to the alternate GW.

See man dhcpd.conf
Add a "router" specification for each MAC address to set it's own gateway.
