WebDiffie-Hellman works in a subgroup of integers modulo a prime p.Namely, you have a generator g, which is a conventional integer modulo p.That generator has an order r which is the smallest positive integer such that g r = 1 mod p.The two systems who engage in DH choose private keys a and b respectively as integers in a given range, and the … http://www.internet-computer-security.com/VPN-Guide/Diffie-Hellman.html

I wonder if this is wrongly configured as the 1 policy is the same as the second, but with different lifetimes. Does this mean that the first policy will always be matched as the second is exactly the same? To me this look like someone made mistake as the router will ...
WebApr 10, 2014 · DH with 2048 bits (group 14) has 103 bits of security. That is: If a really secure VPN connection is needed, the phase 1 and phase 2 parameters should use at least Diffie-Hellman group 14 to gain 103 bits of security. Furthermore, at least AES-128 can be used, which has a security of almost 128 bits. However, since AES-256 can be used …
