DigitalOcean firewall blocks StrongSwan traffic when all ports are enabled
I am using StrongSwan to setup a site-to-site VPN between two DigitalOcean VPCs. For testing purposes I have UFW disabled and when I add a DO firewall with TCP/UDP/ICMP open to all addresses inbound / outbound - ICMP fails to get through the tunnel. Removing the DO firewall ICMP gets through.
UFW works fine in both directions. Any ideas why the DO firewall doesn’t work?
