Could there be a firewall blocking it ?
Actually, this got me to thinking - in the host there isn't any firewall configuration blocking it, but in the network namespace provided by slirp4netns, that might be a different issue. I've no idea where that iptables firewall configuration comes from, but it definitely is different in my setup than the host (which makes sense to me). What the failures are showing for the two who are seeing them is an ICMP response failure from the gateway in the rootless network namespace to the tap0 interface that's defined in the namespace (ie, 10.0.2.2 is the gateway, 10.0.2.100 is the tap0 interface within the namespace). It seems almost certain to be something within this virtual userspace- defined network. -- Jim Henderson Please keep on-topic replies on the list so everyone benefits
