I want to setup link encryption between my Head Office and remote sites. I have heard of two solutions for this. one is IPSec and the other is Tunneling.
Can some one please tell me which one of the above two is better and is there any other techinque that i need to look into. Plus, a working example for this would be really helpful. By the way, i am using DXX, SCPC and Radio Links.
Thanks in advance.
