Wireguard on a DigitalOcean Droplet not allowing ssh, vnc, or smb

EDIT 3/15/22: Config info added at the end of this question I had a WireGuard VPN on a Google Cloud VPN but due to networking fees setup a new one on DigitalOcean. For some reason, I cannot SSH, VNC, or use SMB across any of the devices, but my public IP address seems to be working.

Is this a DigitalOcean related issue or any recommendations for troubleshooting?

This is an example of an error I get when trying to SSH into another device that is a peer to the DigitalOcean Ubuntu Droplet:

ssh: connect to host 10.0.0.5 port 22: Operation timed out 

wg0.conf on the DigitalOcean server:

[Interface] Address = 10.0.0.1/24 SaveConfig = true PostUp = ufw route allow in on wg0 out on eth0 PostUp = iptables -t nat -I POSTROUTING -o eth0 -j MASQUERADE PostUp = ip6tables -t nat -I POSTROUTING -o eth0 -j MASQUERADE PreDown = ufw route delete allow in on wg0 out on eth0 PreDown = iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE PreDown = ip6tables -t nat -D POSTROUTING -o eth0 -j MASQUERADE ListenPort = 51820 PrivateKey = eHXOyd8**REMOVED FOR SECURITY**xMO9mlc= [Peer] PublicKey = wk6iHe+FiJhIV+wLxeCVLyWdT/WV8xrLmeHI39m5v2o= AllowedIPs = 10.0.0.2/32 Endpoint = 104.228.167.16:51820 [Peer] PublicKey = /OEck40Kjc15a3JzePkf9wmlMw+Sdzgaauhfzt/3LkM= AllowedIPs = 10.0.0.3/32 Endpoint = 104.228.167.16:55239 [Peer] PublicKey = CgHsJnocl8CkpD0c4rqFPmOBbpNB8Wpx0hy6J0YhBj0= AllowedIPs = 10.0.0.4/32 Endpoint = 104.228.167.16:59555 [Peer] PublicKey = wxW/6x/M8msXWqahcAR7OjpZbXsZta18qMHGMvbKaRg= AllowedIPs = 10.0.0.5/32 Endpoint = 104.228.167.16:52628 PersistentKeepalive = 25

Thanks to a user in the comments, allowing the firewall to route traffic through the VPN interface fixed the issue.
