Hello Experts,

I was creating some containers with ufw enabled, following is my ufw rules. But for some reason apt get update connection fails when ufw is enabled. When i disable ufw it works. Can i enhance ufw rules to allow this update to work?

Make sure you allow outbound forwarded/routed connections.

Thanks @tomp with the following change it worked for me. Noting down for future readers

DEFAULT_FORWARD_POLICY="ACCEPT" in /etc/default/ufw
