Hi Dennis,

You can see which routing tables are used in which order and for what
traffic with the `ip rule` command.  The routes for each table can be
viewed with `ip route list table <number|name>` (when using `all`
instead of a number or name all routes are listed).  The mapping between
numbers and names is determined by `/etc/iproute2/rt_tables`.

strongSwan will install its routes to table 220 by default (can be
configured via ./configure and/or strongswan.conf) and add a rule to use
that table with a given priority (220 by default, but may be changed
too).  This avoids any conflicts with routes present in the default
routing tables.
