I hit the same issue with the debian9-systemvmtemplate PR. Earlier, the egress traffic option used to accept 0.0.0.0/0.

Thanks Jayapal, Indeed, I checked and 0.0.0.0/0 is not there. When I tried to add it manually I got an error: ipset v6.12.1: The value of the CIDR parameter of the IP address is invalid Hash:net types will not accept 0 prefix, it's happy to accept 0.0.0.0/1 though, however I still can't do any egress except for ICMP ping for some reason. If I omit specifying a a dest CIDR, then I get trully unrestricted egress. I need to investigate some more when I get time, something's fishy. -- Sent from the Delta quadrant using Borg technology!
