Hi jarod,
Could it be that ipmasquerading is only set up in one direction, allowing your netbook-YNH (wg-client) access outbound, but “the internet” not inbound via VPS-YNH (wg-server) ?
A while back a forum member was struggling with the same setup. I was not able to conclusively help out; pointing to rungeard’s post seemed to give the best chance of resolving the issue.
Edit: out of interest: what makes you not use DNS with your dynamic IP?
