Re: GRE Tunnels without IPSEC risks.

Thanks, All.

These are Aruba APs and controllers. 

Just so I'm clear - This is a VPN connecting the remote office to the main office, so I'm assuming it would still be 
encrypted inside this over the Internet? But then the GRE encapsulation would offer no additional protection so the 
traffic would be accessible to anyone who can sniff either side of the VPN (i.e. on the inside at either office) ?

Does that sounds right, or is it worse than this?

Thanks again!

Securing Apache Web Server with thawte Digital Certificate
In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.  We look at how SSL works, how 
it benefits your company and how your customers can tell if a site is secure. You will find out how to test, purchase, 
install and use a thawte Digital Certificate on your Apache web server. Throughout, best practices for set-up are 
highlighted to help you ensure efficient ongoing management of your encryption keys and digital certificates.
