Ok I made my changes to the options file.  However I'm wondering if perhaps
now I have a firewall issue.  Today I am trying to connect to the vpn from a
client site.  At this site they have a very basic ruleset that allows all
traffic out and responses back in.  I'm not what the sequence with pptp is
however the syslog capture below seems to indicate that perhaps the traffic
may be getting stopped by the firewall.
