You have two LANs connected via a router. Network 1 has a DHCP server with a single Ethernet interface. Network 2 does not have a DHCP server. You want the hosts on Network 2 to be able to get IP addresses from the DHCP server on Network 1. What should you configure

You can connect to the DHCP using manual addressing if there is only one interface for ethernet on Network 1

Explanation:

For a device to connect to the Internet, it requires an IP Address, Subnet Mask, Default Gateway and DNS.

So, to connect to the Internet for Network 2, you need to manually change the IP addressing but leave other settings the same.

Let's say Network 1 is connected to this network

IP Address: 192.168.1.2

Subnet Mask: 255.255.255.0

Default Gateway: 192.168.1.1

DNS: 192.168.1.1

Then, Network 2 has to be manually configured to

IP Address: 192.168.1.3

Subnet Mask: 255.255.255.0

Default Gateway: 192.168.1.1

DNS: 192.168.1.1

Every other thing remains the same except a little change to the IP Address
