DHCP - Specify a fail over in settings

[seedboxer]

Hi

I am running 2 instances, at 192.168.1. and 192.68.1.3 i would love to specify a fail over in DCHP settings as in 192.168.1.2 failover to 192.68.1.3 and vice versor.

I can specify 2 DNS servers on my asuswrt modem but would like to drop all DCHP onto AdGuard.

Can it be done ?

I don't think we can implement this on our side. Maybe someone can advice existing solutions.

@ameshkov - Example Config via yourlinuxguy.com. Would obviously have to be adapted.

Primary server dhcp.conf:

failover peer "yourlinuxguy"
{
primary;
address 192.168.1.5;
port 847;
peer address 192.168.1.6;
peer port 647;
max-response-delay 180;
mclt 1800;
split 128;
load balance max seconds 3;
}
# Now include the master config file from both machines
# Don't forget to copy it into the chroot section!
include "/etc/dhcpd.conf.master";

Secondary server dhcpd.conf:

failover peer "yourlinuxguy"
{
secondary;
address 192.168.1.6;
port 647;
peer address 192.168.1.5;
peer port 847;
max-response-delay 180;
load balance max seconds 3;
}
# Now include the master config file from both machines
# Don't forget to copy it into the chroot section!
include "/etc/dhcpd.conf.master";

The dhcpd.conf.master on both hosts:

ddns-update-style none;
default-lease-time 86400;
max-lease-time 86400;
option domain-name "yourlinuxguy.com";
option domain-name-servers 192.168.1.3, 192.168.1.4;
option routers 192.168.1.1;
subnet 192.168.1.0 netmask 255.255.255.0
{
pool
{
failover peer "yourlinuxguy";
deny dynamic bootp clients;
range 192.168.1.50 192.168.1.100;
}
}
