OSX VPN Scripts: The built in Mac VPN client doesn't have too many options but you can easily apply custom settings via scripts. Here are some examples of how to customize your VPN connections. Just put these two files in /etc/ppp and customize. Make sure you `chmod 0755 /etc/ppp/ip-up /etc/ppp/ip-down`. For more information, see `man pppd`.
#!/bin/bash
#
# /etc/ppp/ip-down
#
# When the ppp link goes down, this script is called with the following
# parameters
# $1 the interface name used by pppd (e.g. ppp3)
# $2 the tty device name
# $3 the tty device speed
# $4 the local IP address for the interface
