Let's drop the leading IETF or Infix prefixes from tests. Initially the idea was to mimnic the YANG models, but it's difficult to navigate and does not provide any real benefit to developers or end-users. Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
=== LAN-WAN Firewall with Masquerading
ifdef::topdoc[:imagesdir: {topdoc}../../test/case/firewall/lan-wan]
==== Description
Typical home/office router scenario where the DUT acts as a gateway with
LAN-to-WAN traffic forwarding and masquerading (SNAT).

- DUT/Gateway with firewall and NAT
- Test host has two interfaces: a LAN-side and a WAN-side (Internet)
- Test host's LAN interface acts as a client behind the router
- Test host's WAN interface acts as an Internet server/destination
==== Topology

==== Sequence
. Set up topology and attach to gateway
. Configure gateway with firewall and SNAT
. Verify LAN access to router
. Verify LAN services accessibility
. Verify WAN access to router is blocked
. Verify WAN blocks all well-known ports
. Verify LAN-to-WAN connectivity (outbound)
. Verify LAN-to-WAN masquerading
. Verify WAN-to-LAN blocking (inbound)
