Ubuntu laptop as gateway to internet, send traffic back to Beagleboard

I have a PocketBeagle computer board without a wireless adapter of its own. Its only connection is a USB cable to my ubuntu laptop. I am able to ssh the PocketBeagle through this connection over 192.168.7.2.
PocketBeagles are usually set up so that the internet access of the host laptop (192.168.7.1) is shared. I added the host ip as the gateway using /sbin/route add default gw 192.168.7.1.
I can succesfully ping the the laptop, but when I try ping 8.8.8.8 I get no response. However, I can confirm on the Ubuntu Laptop that it is in fact acting as the gateway and recieving the request using
sudo tcpdump -i eth1 icmp and icmp[icmptype]=icmp-echo. Image attached. This leads me to believe the problem is on the Ubuntu laptop. Perhaps it is not setup correctly to return traffic to the PocketBeagle. Please advise on how to fix this! Thanks.
(ps, the Ubuntu laptop can ping 8.8.8.8 on its own and get response)
