hi,

you might want to mask or hide sensitive info such as public IP addresses.

could you post the show version and show run from your cisco router?

try to configure as below

ip dhcp excluded-address 192.168.2.1

ip dhcp pool LAN_POOL

network 192.168.2.0 255.255.255.0

default-router 192.168.2.1

dns-server 194.7.1.5 8.8.8.8

interface g0/0  

description ISP/WAN

ip address 42.243.7.18 255.255.255.252

no shutdown

interface g0/1
