[Openswan Users] Real Life example for passthroug conn

[Paul Wouters]

As people requested this a few times, here is an example of a working
passthrough connection.

In my case, I have an "extrusion", meaning a tunnel with 193.110.157.30 as
leftsubnet and 0.0.0.0/0 as rightsubnet. Now I have another subnet that
terminates on this server, 76.10.144.0/29. Without a passthrough route,
the conn for my extrusion is picked and this is of course wrong. The
passthrough conn is:

conn passthrough-subnet
	# my own public ip
        left=206.248.139.105
	# the subnet routed to me via my public ip
        leftsubnet=76.10.144.0/29
	# this is needed for auto=route
        leftnexthop=206.248.154.102
        right=0.0.0.0
        rightsubnet=0.0.0.0/0
        authby=never
        auto=route
        type=passthrough

This conn now enables people to reach 76.10.144.6 (which is the same ipsec
gateway box as left - in fact this ip is an alias on br0, the internal
interfaces)
