DHCP-Server for separate LAN and link to Router - M4300
Dear Community, I want to achieve the following setup (as per picture in attachment). I have a LAN which is not permanently connected to the Internet/Router and therefore looking for: separate fu...
It's ok with your setup method, but please make sure below key points, otherwise it will cause Client cannot access Internet.
1. On M4300 switch, when you config DHCP Server(192.168.88.0/24), the dns-server IP must be the Router IP=192.168.178.1);
below is example config on M4300 Switch:
interface 1/0/1
routing
ip address dhcp
exit
interface vlan 1
routing
ip address 192.168.88.1 255.255.255.0
exit
ip management 1/0/1 dhcp
ip management source-interface 1/0/1
router rip
exit
router ospf
exit
ipv6 router ospf
exit
service dhcp
ip dhcp pool "test"
dns-server 192.168.178.1
default-router 192.168.88.1
network 192.168.88.0 255.255.255.0
exit
2. On the Router, you need add routing table back to switch M4300 LAN(192.168.88.0/24). And make sure the Router support NAT for this LAN.
example config:
ip route 192.168.88.0 255.255.255.0 192.168.178.11
Hope it helps!
