I’ve set up a VPC with two droplets following the article at https://www.digitalocean.com/docs/networking/vpc/resources/droplet-as-gateway/. I have a problem where backend droplet cannot connect to the Internet through the gateway when firewall is enabled on the gateway droplet.
Firewall rules on the gateway allow access from anywhere on usual ssh, http and https ports. When I disable the firewall on the gateway, backend droplets can connect to the internet without a problem.
What should I change so that backend droplets can connect to the Internet through the gateway with its firewall enabled?
Thanks in advance!

I found that ufw blocks routed traffic by default, so rules need to be added separately to allow such traffic to pass through.
