Your biggest problem will be that with a tunnel originating behind your firewall, all the tunnel traffic through your firewall is encrypted and unavailable for inspection. A site to site tunnel would be much better as then you can apply rules of access, etc. Regards Patton J Roub -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of PIERRE.DUFRESNE () MESS GOUV QC CA Sent: Monday, November 20, 2006 9:47 AM To: security-basics () lists securityfocus com Subject: How safe is a VPN connexion from within an internal network? Hi all! I have been asked to install a vpn client on a workstation inside our network that would access another network through our firewall. Besides the technical details of allowing IPSec traffic through a NATed device, I was wondering how safe is this practice? Is it done often? Once the connexion is established, can a host on the external network access the workstation inside my network, ie initiate a connexion? Should I rather go with a "site to site" vpn connexion? Thanks for your time Pierre ------------------------------------------------------------------------ --- This list is sponsored by: Norwich University EARN A MASTER OF SCIENCE IN INFORMATION ASSURANCE - ONLINE The NSA has designated Norwich University a center of Academic Excellence in Information Security.
