Here is all I have to set up my gateway machine.
I noted you didn't mention ip_forward in your post. That might be the
problem.
Fill in your values for the $VARIABLES noted below.
As I understand it, you can ping the gateway machine from your daughter's
computer. That suggests that packets are going nicely through your gateway
machine. Maybe you are not masquerading these packets, and they are being
rejected out on the internet because they are a private ip number? Wild guess, here.
What do you see with tcpdump? Can your gateway machine ping beyond the
network gateway?

Here is my routing table for comparison.
