Hi Guys,

I am looking at linking in a few external sites to my network using PPTP since
they are all windows boxes. Does anyone know of any big security holes in this
protocol. I know IPSEC is better, but it is going to be easier just to use the
existing software on the machines.

Thoughts and experiences appreciated.
