monitoring remote access

[Daniel Djundjek <daniel.djundjek () wickhill co uk>]

Dear all,

A strange request was put to me....

A company is setting up a number of dial up accounts via an isp for their
employees able to work at home.  Now since they are dialing in via an isp
and not directly in to the main office, the company would like to monitor
the employees activity to ensure they are not doing anything unsavoury(porn,
hacking, abusing company privelidges).

Does anyone know of any 3rd party tools which can send alerts to a central
location for users on a dial up account.  The dynamic ip allocation would be
a problem but is there anything which can cope with this type of request??
