+hl	NS1
+sleep	2
+
+ns2b	ip ad sh

+nl

+hl	NS1
+sleep	2
+
+say	, pasta
+nl
+say	  takes an interface name from the host
+hl	NS2
+sleep	2
+
+nl
+say	- same for routes:
+
+ns1b	ip ro sh
+sleep	3
+say	 slirp4netns defines its own
+nl

+hl	NS1
+sleep	2

+sleep	5
+nl
+nl
+
+say	Let's run a service in the container. We didn't
+nl
+say	configure port forwarding. With default options,
+nl
+say	pasta detects services bound inside and outside
+nl
+say	the container and forwards ports accordingly, so
+nl
+say	we don't need to restart it. Let's restart the
+nl
+say	container running with slirp4netns...

+nl
+nl
+say	What about performance, you might ask.
+nl
+say	For simplicity, we'll measure between init
+nl
+say	namespace (the "host") and container. To do
+nl
+say	that, we need to allow the container direct
+nl
+say	access to the host, which needs an extra option
+nl
+say	in slirp4netns. Let's restart that container,
+nl
+say	while also mapping ports for iperf3 and neper,
+nl
+say	and enabling IPv6 for slirp4netns (experimental)
+nl
+say	too.
+sleep	3

+sleep	5
+nl
+nl
+say	pasta allows that by default, so we wouldn't need
+nl
+say	to touch the container using pasta, but let's
+nl
+say	take the chance to look at passing extra options
+nl
+say	there as well.
+nl
+nl
+ns2	exit
+
+say	Options after '--net-pasta:' are the same as
+nl
+say	documented for the command line of pasta(1).
+nl
+say	For example, we can enable packet captures
+sleep	3
+ns2b	./bin/podman run --net=pasta:--pcap,demo.pcap --rm -ti alpine sh
+sleep	5
+
+say	,
+nl
+say	and generate some traffic we can look at.
+nl
+sleep	2
+ns2b	wget -O - lameexcu.se
+sleep	2
+hostb	tshark -r demo.pcap tcp
+sleep	5
+
+nl
+say	But back to performance now. By the way,
+nl
+say	pasta doesn't detect bound UDP ports
+nl
+say	periodically (only when it starts), so we
+nl
+say	have to pass the ones we need explicitly.
+nl
+sleep	2
+ns2b	exit
+sleep	1
+ns2b	./bin/podman run --net=pasta:-U,5214 -p 5204:5204/udp --rm -ti alpine sh
+sleep	5
+
+nl
+say	In slirp4netns mode, Podman enables by
+nl
+say	default the port forwarder from 'rootlesskit'
+nl
+say	for better performance.
+nl
+say	However, it can't be used for non-local
+nl
+say	mappings (traffic without loopback source 
+nl
+em	and
+say	 destination) because it doesn't preserve
+nl
+say	the correct source address as it forwards
+nl
+say	packets to the container.
+sleep	3
+nl
+nl
+say	We'll check non-loopback mappings first for
+nl
+say	both pasta and slirp4netns, then restart the
+nl
+say	slirp4netns container with rootlesskit and
+nl
+say	switch to loopback mappings. pasta doesn't
+nl
+say	have this limitation.
+nl
+nl
+say	One last note: slirp4netns doesn't support
+nl
+say	forwarding of IPv6 ports (to the container):
+nl
+say	github.com/rootless-containers/slirp4netns/issues/253
+nl
+say	so we'll skip IPv6 tests for slirp4netns as
+nl
+say	port forwarder (on the path to the container).
