# This strongswan-swanctl test is based on:

|
|
# The roadwarrior carol sets up a connection to gateway moon. The authentication
|
|
# is based on pre-shared keys and IPv4 addresses. Upon the successful
|
|
# establishment of the IPsec tunnels, the specified updown script automatically
|
|
# inserts iptables-based firewall rules that let pass the tunneled traffic. In
|
|
# order to test both tunnel and firewall, carol pings the client alice behind
|
|
# the gateway moon.
