Currently vpnc-script is not directly configurable from configfiles.
However, a workaround is to use a "wrapper-script" like this, to
disable /etc/resolv.conf rewriting and setup a custom split-routing:

------------------------------
#!/bin/sh

# this effectively disables changes to /etc/resolv.conf
INTERNAL_IP4_DNS=

# This sets up split networking regardless
# of the concentrators specifications.
# You can add as many routes as you want,
# but you must set the counter $CISCO_SPLIT_INC
# accordingly
CISCO_SPLIT_INC=1
CISCO_SPLIT_INC_0_ADDR=131.246.89.7
CISCO_SPLIT_INC_0_MASK=255.255.255.255
CISCO_SPLIT_INC_0_MASKLEN=32
CISCO_SPLIT_INC_0_PROTOCOL=0
CISCO_SPLIT_INC_0_SPORT=0
CISCO_SPLIT_INC_0_DPORT=0

. /etc/vpnc/vpnc-script
------------------------------

Store this example script, for example in /etc/vpnc/custom-script,
do a "chmod +x /etc/vpnc/custom-script" and add
"Script /etc/vpnc/custom-script" to your configuration.
