There are several settings in /etc/strongswan.d/charon.conf that should be configurable.
install_routes and install_virtual_ip in particular have defaults that tend to cause me grief.

install_routes sets a default route in table 220. If this happens on both ends of the tunnel you end up with a circular route.
install_virtual_ip attempts to install an address on the local interface for the ip used in the tunnel

abferm, could you work out which other settings would be typically employed w/ a syntax proposal. This way we would implement all at once (saving time).

The full list of options is available here https://wiki.strongswan.org/projects/strongswan/wiki/StrongswanConf
I can search around and see if I can find any examples of people changing these options and figure out which are commonly used.
As far as syntax, how does putting them in a subsection of "vpn ipsec" called 'daemon' sound, ie: 'set vpn ipsec daemon install_routes no"

I've found examples of people setting accept_unencrypted_mainmode_messages, cisco_unity, ikesa_table_segments, ikesa_table_size, and init_limit_half_open.
However, reading through the descriptions many of the options sound useful. It shouldn't be too hard to implement all of them, should it?
