DHCP szerver és maszkolás [Megoldva]

Meg, semmi változás, kivéve hogy nincs hibaüzenet.

Jelen pillanatban Így van beállítva :

sudo nmcli connection modify '1. vezetékes kapcsolat' ipv4.address 192.168.9.1/24 ipv4.gateway 192.168.9.2 ipv4.method manual ipv4.dns 192.168.9.2
 

Innen vettem az ötletet :

https://www.slideshare.net/husseinyounis/configure-a-dhcp-server-on-fedorapdf

Szia, a Wifi oldalon van egy router, a ethernet portban pedig egy DHCP klienst futtató kütyü van, azt szeretném hogy hogy a router (amin be van állítva a DHCP) adjon neki IP címet.

Köszi, rendben.

No subnet declaration for enp1s0 (no IPv4 addresses).
** Ignoring requests on enp1s0.  If this is not what
   you want, please write a subnet declaration
   in your dhcpd.conf file for the network segment
   to which interface enp1s0 is attached. **

Not configured to listen on any interfaces!

This version of ISC DHCP is based on the release available
on ftp.isc.org. Features have been added and other changes
have been made to the base software release in order to make
it work better with this distribution.

# WARNING: This file is NOT used anymore.

# If you are here to restrict what interfaces should dhcpd listen on,
# be aware that dhcpd listens *only* on interfaces for which it finds subnet
# declaration in dhcpd.conf. It means that explicitly enumerating interfaces
# also on command line should not be required in most cases.

# If you still insist on adding some command line options,
# copy dhcpd.service from /lib/systemd/system to /etc/systemd/system and modify
# it there.
# https://fedoraproject.org/wiki/Systemd#How_do_I_customize_a_unit_file.2…

# example:
# $ cp /usr/lib/systemd/system/dhcpd.service /etc/systemd/system/
# $ vi /etc/systemd/system/dhcpd.service
# $ ExecStart=/usr/sbin/dhcpd -f -cf /etc/dhcp/dhcpd.conf -user dhcpd -group dhcpd --no-pid <your_interface_name(s)>
# $ systemctl --system daemon-reload
# $ systemctl restart dhcpd.service
