Connecting dev-board to internet via Ethernet cable connection to host pc

Hello i am trying to connect to the internet on my DE10 nano board (running debian) via a ethernet cable that connected to my host pc (Windows 10). Currently i am able to SSH into DE10 board via the ethernet cable by ensuring that the network prefix of the ethernet adapter from the host matches the network prefix of the de10 ip address. However i am unable to ping www.google.com which tells me am still not connected to the internet. I wanted to share my set up process so that you know what i did so far:

First i set up the ethernet adapters IP address to 192.168.2.107, on my host PC the ethernet adapter info is:

Code:Ethernet adapter Ethernet 3:
Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : fe80::ea97:cab3:5d6d:fd4a%24
IPv4 Address. . . . . . . . . . . : 192.168.2.107
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . :
Next on the de10 board i set up the ip address for the de10:
Code:ifconfig eth0 192.168.2.123Next i set the default gate way to 192.168.2.1 because that's the gateway for my wifi router:
Code:ip route add default via 192.168.2.1The command route -ne now returns:
Code:Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface

192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0On my de10 board, ip a returns:

The contents of /etc/network/interfaces.d are default:

The contents of /etc/dhcp/dhclient.conf are default:

#
# This is a sample configuration file for dhclient. See dhclient.conf's
# man page for more information about the syntax of this file
# and a more comprehensive list of the parameters understood by
# dhclient.
#
# Normally, if the DHCP server provides reasonable information and does
# not leave anything out (like the domain name, for example), then
# few changes must be made to this file, if any.
